Cumulative

Hi

iam using

whileprintingrecords;

numbervar q;

q:=q+{@Q.Earned};

to get the cumulative value, which is doing good for one Person_ID,

As my requiremt changed to run for all the Person_ID`s... i want 'numbervar q ' should be 0 when Person_ID changed.

can any one help me,

Thanks,

Krish
