Hi There,
I have a query witch gives me the following result:
Period NumberOfItems
1 13
2 2
3 1
4 1
5 1
6 0
7 1
8 2
9 1
10 6
11 0
12 2
13 0
But now i want the number of items to be cumulative aswell so like this:
Period NumberOfItems Cumulative
1 13 13
2 2 15
3 1 16
4 1 17
5 1 18
6 0 18
7 1 19
8 2 21
9 1 22
10 6 28
11 0 28
12 2 30
13 0 30
How can i do this?
Thnx in advance,
Victor
