Running Totals

Hello,

I have a report with checking for a field to be equal to something and if true then add it to the running totals.  So when I put in the this formula field in it comes up as false, and when creating a new formula field to print off the total here it shows me zero.

Here is my formula:

WhileprintingRecords;

Numbervar WelderTotal;

Numbervar PressTotal;

if left({VENCREW.WorkStationDesc},4) = "Weld" then

WelderTotal = WelderTotal +{VENCREW.Quantity}

Else if left({VENCREW.WorkStationDesc},4) = "Pres" then

PressTotal = PressTotal + {VENCREW.Quantity};

On the other one to print off my total:

Whileprintingrecords;

Numbervar PressTotal;

PressTotal;

Is there something I missing here?

Thanks,
Gerald
