Hi

I'm still struggling with the below as the macro appears to be contantly
looping. I've set it up so if any of the input cells are used it will trigger
the calculations to be performed on the corresponding cell in the same row.

However, excel just freezes and I have to abort the macro.... any ideas?


Private Sub Worksheet_Change(ByVal Target As Range)

If Not Intersect(Range(Target.Address), Range("A:EE")) _
Is Nothing Then

Dim r As Long
r = Target.Row

If Cells(r, "B").Value < "" Or _
Cells(r, "C").Value < "" Or _
Cells(r, "E").Value < "" Then

' The below equation is the original sumif formula I was using in the cell
' =SUMIF($U$4:$BL$4,$A$2,U5:BL5)

' the below perform sumif's on the same range
Cells(r, "I").FormulaR1C1 =
"=SUMIF(R4C21:R4C64,R2C1,RC[12]:RC[55])"
Cells(r, "J").FormulaR1C1 =
"=SUMIF(R4C21:R4C64,R3C1,RC[11]:RC[54])"
Cells(r, "K").FormulaR1C1 =
"=SUMIF(R4C21:R4C64,R4C1,RC[10]:RC[53])"

' this totals the sumif's
Cells(r, "L").FormulaR1C1 =
"=SUM(RC[-3]:RC[-1])+SUM(RC[5]:RC[7])"

' These take the result of the above sumif and multiply it by a unit price
Cells(r, "M").FormulaR1C1 = "=(RC[-4]+RC[4])*RC[-5]"
Cells(r, "N").FormulaR1C1 = "=(RC[-4]+RC[4])*RC[-6]"
Cells(r, "O").FormulaR1C1 = "=(RC[-4]+RC[4])*RC[-7]"

' This gives a grand total of the above three sub-totals
Cells(r, "P").FormulaR1C1 = "=SUM(RC[-3]:RC[-1])"
End If
End If
End Sub
