SumIf?

[Rodrigo Ferreira]

A
15
26
65
55
68

I would some function like this:
S = Sa - [int(Sa/30) * 30]
S -> Sum (total)
Sa -> Last Sum (column A)

I hope somebody understand... Cause I don't know how can I explain in
English...

Are you trying to create series of numbers?
Starting with 15, 26, 65, 55, 68, following numbers are generated
according to formulas you give?
