Suppressed data still adding to totals

[a_cconsulting]

I've suppredded data in section expert using the following formula under the X-2 button in Crystal Reports v10:

//This formula suppresses the Details line
//when there are duplicate values contained in the fields.
{AR_TRANS_O.INV_NO} = Next({AR_TRANS_O.INV_NO}) And
{AR_Trans_Open.Balance} = Next({AR_Trans_Open.Balance}) And
{@date} = Next({@date})

The suppression worked fine, but the suppresses data is still being added to the sum at the bottom.

Can anyone tell me how to excluded the supressed data in the sum, I've tried a running total, but when i pass the total to the main report, it gets skewed. It won't paas through clean.

Any suggestions?
