excel - How do I apply a SumIf Formula in a VBA Sub? Getting Error 1004

Question

I am trying to create a Sub that places a SUMIF formula in a cell. I have reduced the problem to a simple setup:

Private Sub CommandButton1_Click()
Cells(2, 3).Formula = "=SUMIF(A1:A5;D1;B1:B5)"
End Sub

I get a 1004 Error.

I can run the same code but with the SUM function instead:

"=SUM(B1:B5)"

This does not produce an error. Thus I suspect the semicolons in my formula.

Answer 1

.Formula accepts formulas in English.
Parameter separator in English is ,.

If you want to use formulas in the language of your Excel installation, use .FormulaLocal.

However to ensure your code will run on any Excel, fix your formula to be in accordance with the en-us locale.
