In C2:
=IF(COUNTIF(A$2:A2,A2)1,"",SUMIF(A:A,A2,B:B))

This will give you totals as the first instance of a repeated value. Note
that if your data is sorted, you might also want to look at Data -Subtotal as
a way of quickly summarizing your data.

Hi-

I'd need a formula in colum 'C'. If the number in colum A is matched, then
sum-up the total,e.g 20 in column C; else return value in column B, e.g 5,
and 15.

A B = c
2006 10
2006 10 20
2111 5 5
2112 15 15
