Hi,
I am using Subtotal OK, but here is code for that:
Selection.Subtotal GroupBy:=2, Function:=xlSum, TotalList:=Array(4, 5, 6, 7, _
8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26,
27, 28, 29, 30, 31, 32, 33, 34, _
35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53,
54, 55, 56, 57, 58, 59, 60, _
61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73), Replace:=True,
PageBreaks:= _
False, SummaryBelowData:=False

As it is easy to see running numbers are the problem! It is increacing by
weeks. How could I made a code that would check the amount of columns used
and automatically adding this array?

Something similar to this (arrlist):
Selection.Subtotal GroupBy:=2, Function:=xlSum, TotalList:=arrlist,
Replace:=True, PageBreaks:=False, SummaryBelowData:=False

Thanks in advance
