In MS Access 2010, assume a query contains the following results:
Date Activity Hours
1.9. Reading 1
1.9. Writing 2
2.9. Reading 1
3.9. Talking 1
4.9. Reading 3
1.10. Talking 2
1.10. Writing 1
2.10. Reading 2
3.10. Talking 2
4.10. Reading 1
the Report should show the sum of hours spent each month grouped by activity, something like
Month Activity Hours
September Reading 5
Writing 2
Talking 1
October Reading 3
Writing 1
Talking 4
using the wizard I mange to get a report which looks like
Month Activity Hours
September Reading 1
Reading 1
Reading 3
Writing 2
Talking 1
October Reading 2
Reading 1
Writing 1
Talking 2
Talking 2
which is nearly what I'd like to have but.. ?
I tried =sum(Hours), but then all Hours fields simply contain the total sum of all hours, and I still get several lines for the same activity.
Actually the report is more complicated. In a form prior to the report, the user can enter a date range (e.g. September 1 - October 30). The report should sum over the whole time range and not break up to months, that is:
Date range Activity Hours
9/1 - 10/30 Reading 8
Writing 3
Talking 5
