found it, the file was shiprates.asp which calculate number of packages for all providers.  so I pulled the variable after the include of that file and I am golden.  if anyone has questions on this let me know.

I recommend that productcart allows for added integrated fees to be calculated per package instead of per shipment, because UPS does charge per package $4.25 for signature required/delivery confirmation, not per shipment.

Yes, so same as front end , but this time pull

pcCustSession_OrdPackageNumber from pcCustomerSessions table.

then multiply by handlinfee in the same area as the backend file, except in opc_chooseShpmnt.asp .

It works!

I was able to change the back end (edit order view real time rates) already, but need file location on the front end (shipping cart side)

I pulled ordPackagenum to checkRealtimeRates.asp and I changed the following code:

Changed ---

tempRate=(cDbl(tempRate)+cDbl(serviceHandlingFee))

to

multipleboxhandlingfee=cDbl(servicehandlingfee)*cDbl(dwgordPackageNum)
 tempRate=(cDbl(tempRate)+cDbl(multipleboxhandlingfee))

So what I'd like to try to do is find where the "serviceHandlingFee" is added to front and back end of orders, so that I can multiply the serviceHandlingFee set for the shipping service by the number of packages on the order, and add that number to the integrated rate.

I.E. the built in handling fee per shipping option becomes a "per package" fee, instead of a per shipment fee, which better matches how UPS adds fees, as they add fees per package, not per shipment.  so if you add delivery confirmation and signature required to a shipment, UPS charges per package, and currently productcart  built-in shipping integration rate return does not account for this.

My plan is to add code that multiplies the number of packages x the additional fees value, to add the correct amount to UPS to account for fees per box, that UPS charges, instead of fee per shipment.
