I am working on creating a macro that creates a running total based on criteria in a neighboring column. I’m able to do it with a combination of formulas but I would like to be able to do it in VBA. The code I have thus far can handle it with a few rows, but not more than 4.

```
LastColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column
LastRow1 = .Cells(.Rows.Count, 1).End(xlUp).Row
.Range("O1") = ""
If LastRow1 = 1 Then
MsgBox "No Closed-Won for " & RepName
ElseIf LastRow1 = 2 Then
.Cells(2, LastColumn + 1).Formula = "=F2"
ElseIf LastRow = 3 Then
k = 0
For k = 3 To LastRow1
.Cells(k, LastColumn + 2).Value = Month(Worksheets(RepName.Text).Cells(k, 8))
Next k
.Cells(3, LastColumn + 1).Formula = "=F3+O2"
ElseIf LastRow1 = 4 Then
.Cells(2, LastColumn + 1).Value = .Cells(2, 6).Value
.Cells(3, LastColumn + 1).Formula = "=F3+O2"
.Cells(4, LastColumn + 1).Formula = "=F4+O3"
ElseIf LastRow1 > 4 Then
.Cells(2, LastColumn + 1).Value = .Cells(2, 6).Value
.Cells(3, LastColumn + 1).Formula = "=F3+O2"
Call Q1
Else: 'do nothing
End If
```

(This is the snippet of code that handles that particular action) I think there must be a better way to do this but I am not sure what it is. Any ideas would be appreciated.

The formula to use in cell C2 is

```
=IF(B2=B1,C1+A2,A2)
```

and copy down as far as required

The code to create that formula (if you must) is (Excel will take care of updating the cell references)

```
Sub Demo()
Dim rng As Range
Dim ws As Worksheet
Set ws = ActiveSheet
With ws
Set rng = .Range(.Cells(2, 1), .Cells(.Rows.Count, 1).End(xlUp)).Offset(, 2)
rng.Formula = "=IF(B2=B1,C1+A2,A2)"
End With
End Sub
```
