Dear All,
I have the following table:
A B C D E F
1 No. Hours Price/m² Price/hr Total price Total m²
2 20140 8,50 0,08 20 170,00 ‚¬ 2125,00
3 20140 9,15 0,08 20 183,00 ‚¬ 2287,50
4 20140 6,00 0,85 20 120,00 ‚¬ 141,18
5 20140 8,50 0,85 20 170,00 ‚¬ 200,00
6 20170 8,00 0,08 20 160,00 ‚¬ 2000,00
7 20170 8,50 0,85 20 170,00 ‚¬ 200,00

And I need to get automatically report which will sum up "Total m²" and
"Total price" of those with the same "No." and the same "Price/m²".
In other words the report must look like the following:

A B C E
1 No. Total m² Price/m² Total price
2 20140 4412,50 0,08 353,00 ‚¬
4 20140 341,18 0,85 290,00 ‚¬
6 20170 2000,00 0,08 160,00 ‚¬
7 20170 200,00 0,85 170,00 ‚¬

I was able to sum up bz using just one criteria "No." but when it comes to
two criterias I failed.
I'd greatly appreciate zour help!
Rgds,
Ruslan
