# One Array Formula To Sum Product With Weighting Data

Jun 11, 2014
My problem is a little more complex than sumproduct.

I have a ratings column and exposure column. I want to weight those ratings before doing a sumproduct, at the same time ignoring #value.

In the attached file, I want to achieve the green cell in one go, based on the orange raw data.

I am trying to use a PRODUCT formula to return the product of a list of numbers in a column, between 2 specified dates. The spreadsheet is arranged as follows:

Column BA list of dates

Column C & DNumerical data not used in any calculations

Column EThe numbers to multiply together

Cell A1Start date to be used in the PRODUCTformula

Cell A2End date to be used in the PRODUCT formula

The formula I have to multiply the data in column E, subject to the start and end dates in Column A is:

{=PRODUCT(IF(B15:B1000>A1,IF(B15:B1000<=A2,INDEX(B15:E1000,0,4))))}

This returns zero though works appropriately if I replace “PRODUCT” with a “SUM”.

The data is arranged as such, there are a list of call types and in another column, there are a list of call lengths. Currently I have a COUNTIF which searches the call type column for certain call types ie BA is off peak but this only tells me how many off peak calls they have made, I need to make it tell me how many minutes of off peak calls there are.

IE this is an example

Call Types Call Lengths (minutes)

BA 1

BA 1

BA 3

BA 2

at the moment my formula would only count this as 4 but I need it to calculate it as 7. This is a very big data set containing around 900 entries per sheet.

I've gotten were Cell formulas.

I need this for VB code, for an array that is the product of another macro hence it's dynamic.

B 3

E 2

E 8

D 2

B 1

B 7

How do I subtotal Col A,B according to Col A?

Total 3 B entries with a subtotal of 11

Total 2 E entries with a subtotal of 10

Total 1 D entry with a subtotal of 2

I'm working on a order spreadsheet system, and I have one sheet called Product Details, where the product name, list price and product code are found, these link to the Sales order page, and I need them so that they can be added to.

So far, I have created a dynamic named range for the Product name on the Product details sheet, and linked the the range via a list validation on the Sales order sheet.

The drop down list displays the products and can be added to by typing new product names on the other sheet.

What I need now is that when a product on the sales order page is selected, it draws the the list price and product code data automatically from the sheet, I tried using a normal vlookup, but I couldn't get it to work. I also need the list price and product code columns to be 'dynamic' so new values can be added further along.

I would like to have a Macro to go from the first tab called "Start" and end up with the second tab "End" automatically. BAsically I need to take the product on each line under Tab Start and reproduce it for sizes 35-41 always ending with "-(size)". Then this new Product with Size needs to be multiplied one below the other for as many times as I have pictures (number shown under column B of the tab Start). Next to this value in column B of tab End I'd like the same name listed again but with the number 1, then 2, then 3, etc. as needed and the extension .jpg.

I have a Sumproduct formula that should be resulting in 0. However, it is resulting in a very small number. I have 2 columns of data. The first one contains -169.5, -123.4, -34, -67.4, 169.5, 123.4, 34, and 67.4. The second column contains all 1's. When I create the following formula, =SUMPRODUCT(H27:H35,J27:J35), it results in 5.68434E-14.

Sometimes, when I have different numbers in the first column, but it still adds up to 0, the Sumproduct works.

What I need to do is count the number of cases and values of everything written between the first of January and today (242).

I know how to do it by counting the days from the 1st of Jan to today but how can I do it so it automatically updates each day.

This is what I have at the moment.

The product name is in K, the date is in H and the value is in M. The range is from cell 7 to cell 94

=SUMPRODUCT(--($K$7:$K$94="Pension"),--($H$7:$H$94<=TODAY()),--($H$7:$H$94>=TODAY()-242),$M$7:$M$94)

The following formula takes a census of people in our area by date and by hour (sample data attached): =SUMPRODUCT(--(FLOOR(Data!$B$4:$B$39,1/24)<=$B2+C$1)*(Data!$C$4:$C$39>=$B2+C$1))

The formula works great, but I would like to add another component whereby the census will only count someone if they have a certain description (see column A - with color descriptions). So how can I setup the formula, to say, only look at the "red" colors during the same specified dates/times and give me the same type of census...instead of looking at all of the data or creating 50 different ranges for all the colors?

I am stumped on coming up with a dynamic formula that calculates a value based on an increasing number of "sums of products". Specifically, I need to calculate the total number of repeat users based on a "decaying' repeat rate. In other words, I need it to calculate = Sum[... +(d5*f5)+(d4*g4)+(d3*h3)]

or in equation form:

where

n = (1, "infinity")

and

i = {1, 2, ... (n-1)}

with

"Xn" is the calculated value of repeat users for month "n" (output/result cell)

"mi" is the number of new users (in month i)

"Nn-i" is the column 'number' of the repeat rate value (%) multiplier

Here is a screenshot of the first couple rows to illustrate:

I actually have about 70 months of data (rows) and roughly the same amount of columns representing a decaying repeat rate (70 or so) and these will be increasing as time goes on so I need this formula to be dynamic (i.e. - copy it down the column of (# of repeat users)

I am using Excel for Mac 2011.

I currently have a formula that totals a product between two dates, however I need to add up a reason code for that product also in a different tab. My current formula is

=SUMPRODUCT(--('Product'!$A$2:$A$1069=B6), --('Product'!$B$2:$B$1069=Data!$A$1))

I want to add another section so that it looks at the dates between C6 & B6 and also the product in Data A1 but totals the reason from cell C10 in the data worksheet.

i need to look up a product based on the number and the qty. see the example attached.

On tab "Printer - S" 1 need to lokup the costs based on the product code 8 and the qty 100. How do i do this and make it adjustable for any range of priduct codes and qtys. Again, becuase this will be used on a Mac Office, i cannot use macros.

Basically I have in the first column, different products (lets call them a, b,c and d). in the second column is a counter which starts at 1 and continues counting down the column.

In the third column I need to identify if it is the last time the product has been run. i.e there are no more duplicates of product a further down the 1st column.

I have attached an example : example.xlsmâ€Ž

I'm trying to get a cell {in the attached spreadsheet 'Order Form' Sheet- Cell 'B13'}, to bring up the corresponding product description {'Products' Sheet- Column C}. For the cell that is to bring up the product description {'Order Form' Sheet- Cell 'C13'}, the following is the formula I'm trying to use, but is coming up "#N/A":

=IF(C13>1000,VLOOKUP(A13,Products!$A$2:$D$12,3),IF(C13>287,VLOOKUP(A13,Products!$A$14:$D$25,3),IF(C1 3>0,VLOOKUP(A13,Products!$A$28:$D$38,3)," "))).

I haven't attempted the "Cost/Bottle" formula yet {'Order Form' Sheet- Cell 'D13'}, but it needs to correspond the product number {'Order Form' Sheet- Cell 'A13'} and the quantity ordered {'Order Form' Sheet- Cell 'C13'}, with the cost/bottle on the that quantity found on 'Products' Sheet, Column D.

In the first sheet I have two columns, one for the product_id and one for the name of the product. So the Sheet1 is like a small database. The second sheet is for the orders.What I want is when I type the product id in the A column of the orders sheet(Sheet2) to auto insert the product name in the B column so i dont have to write it every time.

I need array as my data source is a form & new rows will be added everyday. I want to do that by formula not using spreadsheets 'Filter" option.

Expected result will looks like below (All Nov-13 rows will return)

see attachment. I would like to calculate the average of the values whose time values fall in between the lower and upper time limits. Or let me rephrase that: If a given amount of time vector entries falls in between the lower limit time vector (at row x) and the upper limit time vector, then I would like to calculate the average of the corresponding value entries. (oh, not only the average but also the standard deviation)

Searching the forum I found a similar entry, but unfortunately Andy Pope's solution attachement seems to be missing: [Solved] Formulas: Counting within bin sizes. I have tried to use the same approach (see attachment) but only came up with counting the frequency instead of calculating the average.

I'm trying to set a cell on one sheet to be equal to the product of two cells on another sheet. The problem is that one of the cells on the other page is dependent on the variable T. This is what I've got and it's giving me errors

Worksheets("Output").Range("K14").Formula = "Worksheets("Calcs").Range("D17")*worksheets("Calcs").Range("D17").Offset(10+T,0)"

When I record a macro it gives me this, but again, I need the last cell in terms of "T"

ActiveCell.FormulaR1C1 = "=Calcs!R[3]C[-7]*Calcs!R[14]C[-7]"

I often have to research long sheets of data, which requires filling data in on my research sheet from several different sources. The research sheet has a file # in A and a vendor # in C. The data sources have the file #s & vendor #s in varying columns, but I use a pivot table to end up with file # in A, vendor # in B and the needed data in C.

The length of the research sheet varies from month to month - often 800-900 rows, so you can imagine how tedious it is to find the correct file #/vendor # combination to plug the data in. (Many of the rows on the research sheet will not have a row on the data source sheet.)

I managed to get an array formula in one of the columns on the research sheet that actually DOES work:

Code:

{=INDEX('Acct Activity'!C$1:C$7,MATCH(A7&C7,'Acct Activity'!A$1:A$7&'Acct Activity'!B$1:B$7,0))}

But the problem is that it returns #N/A in any row that doesn't have any data. This messes up the sum formula in the farthest right column. So, I tried to incorporate an ISERROR in with the formula, but couldn't get it to work; it left all the cells blank.

In the meantime, I got to thinking that, since there are up to 3 columns requiring data on the research sheet & each column's data comes from a different source, wouldn't it be great to have a macro where I could use a couple of Input Boxes: 1 that would let me click on the column where the data NEEDS to go & 1 that would let me tell it (either by typing the worksheet name or by clicking on the worksheet " PREFERRED " where the data come from)!

So, I spent the entire day yesterday trying to make any of that work & can NOT figure it out! I got the macro to pop up the first input box, & can key in the column letter, but clicking OK doesn't do anything. Yesterday, I had it so I could click OK & the box would go away, but nothing else happened & the second box wouldn't work right.

THEN, I started trying to figure out how to do an array formula in a macro & my head nearly exploded! I have a terrible time trying to understand written descriptions if they're in "tech speak", so it was all greek to me.

Here is all the farther I got with the macro:

Code:

Sub ClearingRsch()

' Jenny 10092011

With Application

.ScreenUpdating = False

.EnableEvents = False

.Calculation = xlCalculationManual

.DisplayAlerts = False

I have column E listing all of the favorites and column G the underdogs, each row represents one game, there are 34 all together. I want a formula to pick the team based on a random generation. That part i have....

=choose(randbetween(1,2),e7,g7)

but here is the rub.

I only want the total number of underdogs to be 20% and the favorites to be 80% of all of the picks.

I am not sure it can be done as each formula must look to what the other formulas are doing...aside from it being circular i think it just impossible or i am not as advance as some of you.

I have two factors that both change, resulting in two unique values. I'm trying to determine which portion of the resulting delta is attributable to each factor. Example:

Hourly Cost Run Rate Piece Cost (Hourly Cost / Run Rate)

$105.00 4,500 $0.0233

$126.10 3,000 $0.0420

Two unique results titled Piece Cost = Delta

$0.0420 - $0.0233 = $0.0187

How much of the $0.0187 is attributable to the change in Hourly Cost and how much of the $0.0187 is attributable to the change in Run Rate?

I am trying to get my array formula to recognize the text selected in my data validation cell. The formula worked perfectly until I decided I wanted to try and use a data validation list to eliminate spelling errors. Even though the text I am trying to recognize in the cell is exactly the same, because it is in a data validation format it no longer works. Is there a way I can modify my formula so it works? Example below...

formula: {=SUM((A2:A109>DATE(2013,10,31))*(H2:H108="Joe Blow"))}

A2: 11/2/2013

H2: Joe Blow (chosen from a data validationi list)

The result of the formula should equal 1 in this example, or more if the same criteria occurs more than once within the range of A2:A109, and H2:H109.

I have 11 months of sales commission data, and need to estimate the value for December. However, the catch is, for the first 7 months, the values are significantly higher than the most recent 4 months. I'm currently using the TREND function to guesstimate the December value, but with the wide fluctuation between the 2 time periods, I'm thinking the result of the TREND value may be way off.

Is there a way to 'weight' the data to reflect the higher values earlier in the year, with the much lower values later in the year?
