VBA Function for a Sumif
Hi All,
I have been asked at work to produce a formula which will do a sumif on a range in a single row where the criteria are in adjacent cells.
For example 20,1, 10,1,15,2
The result would sumif if the cell to the right is 1 - giving an answer of 30 in the above array.
I am struggling to produce a formula that can do this so I have gone to a custom function. What I have is below (which doesn't work)
Public Function MattsSumIF(Criteria As Double, NRange as range)
Dim Cell As Range
Total = 0
i = 1
For Each Cell In NRange
If ActiveCell.Offset(0, i).Value = Criteria Then
Total = ActiveCell.Value + Total
End If
i = i + 1
Next Cell
MattsSumIF = Total
End Function
Any ideas?
Thanks
Matt

How about this formula, assuming your data is in range A1:F1

Additional notes:
1. Bad editing note:
You don't need to Dim Cell (left in when editing your function)
Should read: Dim Total As Double, i As Long
2. Error handling:
If the data is always correct (i.e. what you are summing is numbers) the above will always work. Typo's resulting in Alphas in the sum cells will return #VALUE error (which you probably want in order to highlight data errors). The criteria cells can be alpha-numeric...
If you use the standard Excel array I provided, it will sum the result and ignore alpha’s (like a standard SUM does). If you want to use your function but achieve this result (i.e. ignoring alphas), Insert "On error resume next" as the first line in the code after the Dim.

Thanks NeillZ - works a treat!
Just a quick idea, use Cell instead of ActiveCell.
