Hi There,

I am trying to make a PT with a source of 25.000 lines on 17 Fields,
among which one field is called "UNITS"and another "Country"

I just try to sum the number of Units by Country but it just shows me
0 everywhere.
On a smaller "sample" (eg. 1000 lines) I get a result ...

Any ideas what's wrong and how to solve this?

Thanks in advance!
