Hi All--

I have a issue and I wonder if anyone has ever come across it before.  I want to create two opportunity level custom fields that sum up different products associated with the opportunity.  I.E., Opportunity Custom Field A sums the amounts of products 1,2 and 4; Opportunity Custom Field B sums the amounts of products 3 & 5.  These are different types of products (software and services,) so you should be able to look up by the names.  

I've tried this a few different ways, using both custom fields and s-controls and I can't seem to get it.  Any suggestions?

Thanks,
BW
