>In the detail band of the repoprt designer I display records, each having a field namend 'nAccepted'
>
>In the summary band I display the Total of the 'nAccepted' field by selecting SUM in the "Calculations" option of the "Properties" window of the expression.
>
>I need to use the value of the SUM (in the Summary band) in another expression in the Summary band of the report. The other expression is: nPercentage = (nAnotherValue / the sum of nAccepted==>*SUMmed from the Detail band).
>
>Is this possible?
