Hello.
I have a table that stores information as follows:

Field1            Field2               Field3
a1             01/01/2005             3
a1             02/01/2005             8
...                    ...                    ...
a1             07/01/2005             5
a2             03/02/2005             6
...                  ...                      ...
What i need to do is to create another table with just one line for a1, a2,
etc, that stores the sum of field3 but only for working days starting from
the first date that appears for each record. For instance, for record a1 i
want the sum of field3 of 5 occurences but excluding Weekend days.

Is this possible?

Thanks
