Product Comparsion help!!

[alloysmith77]

The following form code info at the bottom will look up parts within
our recordset hardware category search:
The search form is divided up by search by Part number, by OEM #,
Keyword, and Company Harware Name. I want to add a section to the form
that will allow customers to enter a search by Part Number of 2 to 4
products for a direct side by side comparsion. Just need to what is
needed to proceed with this task. Or if there is a site
that has a tool to do this:
