Iteration

Feb 10, 2009

Suddenly I have a problem with copying formulas:

I started with the following formula: =COUNTIF($D2:$D5694,D5724)
I then copied it to the next line: =COUNTIF($D3:$D5695,D5725)

That's not supposed to happen if you use the $ sign. So I checked Tools > Options > calculation. That is set to automatic. What else could cause my problem?

Reset For Loop On Each Iteration?

Jul 2, 2014

I want to iterate a For Loop changing one variable each iteration until the Total from the For Loop equals zero. Each iteration of the Do Loop keeps the previous Total from the For Loop and adds it. How do I reset the For Loop to start from Total = 0 at the beginning of the For Loop?

Sub PV_IRR()
Discount_Rate = Range("A2")
Total_Investment = Range("B2")
Annual_Return = Range("C2")

[Code]....

Utilizing Iteration In Conjunction With Function

Nov 1, 2008

I would like to start with a spending value, (SV), that would be the amount of money that I want to spend in a year, not counting taxes. The function (or functions) would then go through some sort of iterative calculation process that would compute the total spending level including taxes, (TS), the federal tax, (FT), and the state tax, (ST).

These values would have the relationship that TS=SV+FT+ST. When the iteration was finished, the federal tax and state tax amounts would be consistent with the taxes that would be due for this level of total spending as determined by the normal tax tables for both federal and state taxes.

I am not concerned that the tax figures be absolutely exact, so a lot of iteration is probably not necessary.

Generate Iteration Number Of Countif?

Jan 24, 2013

I'm looking for something one step deeper than a countif. I need something that will tell me what iteration number it actually is within the countif, in relation to date, as shown.

Any formula that could be used to do something like this?

Call Function At Each Iteration Of Solver

Mar 27, 2008

I have a written a small sub to run solver. However, I need to run a secondary sub at each solver iteration. The secondary sub I want to run is called “BypassGoal”.
My code currently looks like:

Sub OperatingPt()
Dim WrkBk As Workbook
Dim WrkSht1 As Worksheet
Set WrkBk = ThisWorkbook
Set WrkSht1 = WrkBk.Worksheets("Engine")
Dim Mode As String
Dim CellTarget As String
Dim CellRange As String
WrkSht1.Activate
WrkSht1. Cells(30, 2).Value = 2
CellTarget = "H14"
CellRange = "B30"
SolverReset
SolverOptions Iterations:=3000, Precision:=0.000001, AssumeNonNeg:=True, Derivatives:=2, StepThru:=True ....................

Code Loops Through Range Instead Of Crashing On Second Iteration

Apr 6, 2014

Not come across this issue before where the Code works once then fails to iterate!

In attached file 140405 Loop not working.xlsm, for each cell in C4:C27 on the Inventory Sheet, the Code should:

Look in the Data Input sheet.

Find the Item Number in Col B corresponding to the number in Col A of the Inventory Sheet.

Find the quantity on the Data Input sheet corresponding to that number.

Copy the quantity into Col H of the Inventory sheet.

The Code works for the first row then throws error message "Run Time error 13" Type Mismatch!

VB:
Sub OFFLOAD()
Dim Dest As Range, Dest1 As Range, oCell As Range
Set Dest = Sheet2.Range("C:C")
Set Dest1 = Sheet2.Range("B:B")

Sheets("INVENTORY").Select

[Code] .....

Error In Code Regarding Iteration Through Multiple For Each Loops

May 23, 2014

I am having some trouble with some code I am trying to write for some calculations. I am trying to make excel iterate through a range of cells in 2 columns and compare the cells in each row of the column to a set different number. If both the numbers in the row pass the test then I add them to a count. I know it is simple but I am really struggling with my basic vba knowledge to correctly iterate through 2 columns.

A
B

5
8

8
4

2
9

9
9

For example say my "cutoffs" are a value greater than 2 for numbers in column A and a value greater than 5 for numbers in column B. The program then should return me a value of 2 for this example.

Option Explicit
Function cutoff(phi_cutoff As Double, sw_cutoff As Long, gross As Double)

Dim count As Double
Dim my_range1 As Range
Dim my_range2 As Range
Dim c1 As Range
Dim c2 As Range
Dim value1 As Double

[Code] ............

Calculate Temperature Values Directly For 10th Iteration Without Solving Each?

Nov 13, 2013

I had 4 initial temperature values and after some time i got new temperature values. Now for calculating 2nd iteration i need to use new calculated values and for third iteration values from 2nd iteration is to be used and so on.

How to calculate temperature values directly for 10th iteration without solving each iteration?

Iteration Inconsistency: Allow For A Cost Being Added To Loan Amount Where The Cost Is Based On The Total Loan Amount

Mar 15, 2007

In a financial environment we have a calculator which uses iteration to allow for a cost being added to loan amount where the cost is based on the total loan amount. Iteration is set to 100 iterations with max change .001

On one PC the first time the calculator is opened it gives a particular (incorrect) result. If the input cells are cleared and the data re-entered, it gives the correct result. This only happens on one particular PC. Is there some other setting , other than the iteration setting, that would cause this?
