Want to add QTY column with "Total QTY"

Trying to take the default "QTY." and add it to my own custom"Total QTY". Right now I created another column labeled "Total JobQTY".

The equation is: 'QTY.'*"\$PRPSHEET:"QTY Total"".

It comes out as: ='QTY.'*"3"...so somehow the equation is screwedup. If I just make the equation 'QTY' then the correct QTY per 1show up.SolidworksBill Of Materials
