Simple question on summing a formula field

Question

I am somewhat new to Crystal and have run across this need for the first time.  I have a simple report that allows for multiple quote numbers to be entered in a parameter, then groups lines by product # and then calculates in that group, the total quantity ordered for that pn.  In that group header, I then multiply the unit list for that pn by that total of qty ordered to come up with a total list for that pn.  I now simply need to Grand Total that group total.  I'm using Crystal 11.
Thank you!

Hmm, if you are using the SelectExpert to only report on the part numbers that you selected in the parameter, then a pair of simple formula would be the simplest way of doing it (although there are others!):
//formula1 - place in details ection and suppress;
whileprintingrecords;
numbervar grandtotal:=grandtotal+(UnitPrice * Quantity);
//formula2 - for the end of the report
whileprintingrecords;
numbervar grandtotal;
If the items on the report are not determined by your parameter choice (ie: still display them, even if not picked), then change formula1 to:
whileprintingrecords;
if QuoteNumber in {?-ParameterList}
then numbervar grandtotal:=grandtotal+(UnitPrice * Quantity);
Or you could just setup a grand total variable, and in your existing formula that does "multiple... ...pn by that total of qty" have a line prior to the end of it that adds "pn * qty" to the grand total variable?
Ideas to play around with at any rate...
