Custom Function, UDF, To Return Nothing Or Empty Text
Jul 16, 2009
I am plotting a chart using data from custom functions. On occasion, the formulas return erratic values (due to the underlying data) which I wish to exclude from the chart. If the function does not pick up a value in the code, by default it returns a zero.I would like when this happens to have my function return nothing instead of a value - and I mean absolutely nothing, not a blank string. in this way, the chart line will totally ignore this point.

I'm trying to create a user-defined function, but the function needs to know what cell it has been placed in. I want to use this cell reference to get some other offset values. I can easily find out offset values based on the ActiveCell, but not for those offset values based on where the UDF is actually placed, which could be almost anywhere on the worksheet.

I am performing a lookup using the populare user defined function nlookup, which does not take a lookuparray argument to find lookup values. But I only want to return lookup values that fall into a certain array. To accomplish this, I figured out that I need a way to specify a condition of the type "if cell address of lookup value falls within range"
It should be possible if I find a way to return the cell address of the nlookup value, but as nlookup is not limited by a lookuparray argument, so I was not able to use the address/index/match that come up in similar questions.

I have a cell with a text string >3, and would like it to return the number (not text) 3. I could use Right but since the number will not only be single digit I don't think this will work.

I am using a MID fn to extract a single digit from a numeric string. I then use an IF Function to return a value based on the extracted digit. My IF statement works fine on manually entered digits but doesn't recognize my MID fn result. What am I missing?

I have two columns in a spreadsheet that I want to use an IF function with. In the first column, I want a pick list containing 5 text options. Depending on which option is chosen, I want a number to auto-populate in the second column.
The numbers are important, because I want to repeat this pair of cells with slightly different text values in the second pair, and then to have a column that multiplies the two resulting numbers and conditional formats the result.

I need code for a search box function, that returns the information recorded in a cell for example, "Barcelona" or "London" etc), instead of the location of the cells.
I will need to narrow it down to search only the information in the following columns:
Sheet2
I2:J10932
I am totally new to VBA coding and have stumbled my way through a few things, but everything I have searched for so far has had at least one error when transposing to Excel.
I am running Excel 2007.

Is it possible to make a cell "really" blank/empty based on an If statement? For instance:
=if(a1>10,a1,"")
Has a value_if_false of "". But Excel interprets this a bit differently than a cell that never had anything typed into it.
So if you have a column full of this formula copied down, and hit <control+down arrow>, you will go straight to the bottom and skip over all rows. Whereas if you have a column with values and empty cells alternating and hit <control+down arrow>, you will only skip the empty cells and go to the next value. Excel treats the conditionally empty cells as if they have a value, when it comes to this type of navigation. This holds even if you copy and paste "Values" for the cells over the formulas.
Is there any way to tell Excel to make the cells truly empty?

Hi, I desperately need help with a pivot-table and can't find anyone else who's ever had this problem...I have a very large healthcare data table which for simplicity I will describe as follows. In essence the first two columns respectively are (A) location and (B) month. Let's say the third column (C) is the number of cases of the disease kidpox treated in each health centre during that month. The fourth column (D) is the total number of cases of everything treated during that month in each clinic. The fifth column (E) is the proportion of cases of this disease over all consultations for each health centre and month, and the formula in E2 is .....

Imagine i have 2 columns: Open and Close, both of these got numbers like
1 ---- 2
3 ---- 1
4 ---- 10
and so on. I had to make a function which checks if some number is in between any of those Open and Close numbers and count how many, for example: im searching for number 1.3, so according to previously drawn table i would get answer of 2, because 2 is in between 1----2 and 3-----1, i achieved this by a simple function:
=IF(OR(AND(Bendras!$J$1>=Table1[[#This Row],[Open]],(Table1[[#This Row],[Close]]>=Bendras!$J$1)),AND((Bendras!$J$1<=Table1[[#This Row],[Open]]),(Table1[[#This Row],[Close]]<=Bendras!$J$1))),TRUE,FALSE)
this generated an additional column with TRUE and FALSE values which i counted with:
=COUNTIF(Table1[T/F],TRUE)
and got the answer.
so now then preparations are ready i need to make a function which would for example if the number i was searching was in 10th and 45th rows find the MAX/MIN values of Close column between those rows(hope i made my self clear)
this is how i was hoping to do that : first of all make a new array of all cell addresses from "Close" column which were "TRUE" from the first function i wrote and when do w/e i like with those cell addresses in other functions.

My co-worker created a function that would calculate the standard deviation according to whatever range is selected by the user.
I was hoping to add an if statement to the formula but am getting a #value! error.
coworker's function:
Function volatility(r As Range, Optional scl As Double = 252) As Double
Dim lr() As Double
rws = r.Rows.Count
ReDim lr(1 To (rws - 1)) As Double
Dim variance As Double
[code]....
What I'd like to do with the function:
=volatility(IF((YEAR(A8:A1036)>=K3)*(YEAR(A8:A1036)

I have created a custom Function in excel. I would like to create a custom button so I can run this funtion with a Click of a button unstead of typing it in or clicking on the insert function button. I am not sure if this is possible to have VB call a custom function. Below is my VB for the Custom Function. I basically want the custom button to open the formula in excel.
Public Function CreateFlexstring(Company As String, Cost_Center As String, _
Division As String, Geography As String)
CreateFlexstring = Company & "-" & Cost_Center & "-" & Division & "-" & Geography
End Function

I have a column of data with 2 possible values, "H" or "A". The second column contains numbers (unsorted).
How do I write the VBA code to return the Highest number, where the first column is 'H' ?
Eg.
Location Attendance
H 25365
A 17436
A 47252
H 15494
A 37578
H 17549
H 28756
A 59756
This would need to return 28756.

I am very proficient at Excel/VBA and have a question about custom/user-defined functions that may be a little more advanced. I understand how to write custom functions and access them through the user-defined functions menu, but I would like to be able to include my function in an add-in that users could simply add, and then access the function via the 'Fx' box at the top of Excel, like they would any other built-in function, instead of having to go to the user-defined functions menu. I guess what I am looking for is how to add 'built-in' functions and not user-defined ones. I just want the user to start typing '=customFunction(' and have the parameters pop-up in tool-tip form, like any Excel built-in function would.

I have a custom range -55% to 55% as part of a grading system for sales growth. I want to return a 0-100% grade depending on where within that -55% to 55% range a sales reps growth for a month falls. For exaple, if a sales rep scores 0% growth for a month, they will receive a 50% grade by where 0% falls within the -55% to 55% range.

I have a calendar I have developed that highlights the current date and opens by default to the current month. Each worksheet is a seperate month. The current date highlighting is written with a public macro and the opening to current month is a private macro. The problem comes when this workbook is shared and the other users have to agree to accept my macro because of security. I would like to bypass that requirement and just have the workbook stand alone without the permission.

QuarterMonth = "Q1 - 13"

Basically i want to use a UDF to count cells in a range of a certain colour.
But i want to make it easy for the user to be able to change the colour the function counts, so i thought i could ask them to colour the cell in which the function is written.
Is there a way to tell the function to pick up the Interior.ColorIndex of the cell it is written in?
Use Application.caller.interior.colorindex

I am trying to use the AutoFilter/Custom function in Excel (it is available under the Data Menu). It offers me two conditions/criteria that I can apply using and/or. For eg:
Filter:
does not begin with - 3
and / or
does not begin with - 9.
I want to add a third 'and' criteria .. is it possible, and if so, how?
The column that I am trying to filter has numbers formatted as text.

I have created an addin (myAddin.xla) with custom functions in it. In a given cell, my funtion would look something like "=myCustomFunction(A1, B5)".
Periodically, while I'm working with the spreadsheet, I'll do something to a cell and the formulas in all the cells which used a custom function immediately get reset to something along the lines of "=C:...Application DataMicrosoftAddInsmyAddin.xla'!myCustomFunction(A1, B5)". The reset function also causes the function not to work properly and I get a "#NAME?" error in the cell.
I haven't yet figured out what sequence of actions causes the reset (it happens infrequently, but often enough to be a major problem) but it happens while I'm working with the document (i.e., it doesn't seem to be linked to saving/closing/reopening/etc). After I notice the reset, if I go to each cell that uses a custom function and delete everything from "C:... to myAddin.xla!" in the formula bar and hit enter, the function works normally as before.
(Technically, my Windows XP Pro system uses synchronization with a server at work, so the file path is not "C:...Application DataMicrosoftAddInsmyAddin.xla'!" but rather "\myServerNamemyDirectoryDocuments and SettingsmyUserNameApplicationDataMicrosoftAddInsmyAddin.xla'!". I'm not sure if this reset error has anything to do with being connected to the server or not, but figured I'd mention it anyway.)
