Crystal Reports IncorrectTotal Amount

Message

   I have a report that has 3 records. Each records has Total (QTY * Unit Price = Total) and Grand Total for all 3 records.

Rec          QTY           Unit Price           Total
 1              4               42.00               168.00
 2              4                 1.28                   5.12
 3              5                 0.00                   0.00

The report produces a Grand Total of 341.12, when it should produce a Grand Total of 173.12.

When I do a count of Rec or QTY, I get a count of 4 instead of 3. It seems Rec #1 is caculating behind the scene for that additional 168.00.

Any suggestions would be appreciated to resolve incorrect amount.

Thanks,
CoachGBT
