>OK, I give. In a report I created a variable called lnSubtotal and in its value to store I put SUM(viewname.numericfieldname). I received a "'Sum.prg' does not exist". I tried other combinations such as SUM(viewname.numericfieldname) TO lnSubtotal, SUM viewname.numericfieldname, and CALCULATE SUM(viewname.numericfieldname).

You do not use the VFP SUM function this way. Put a field control in the Group Footer or Summary band of the report with that field as the expression. Click the Calcualtions and check the Sum option.
