Portal Form and lookup

Hi

I have a portal form that populates a field from lookup. Lookup displays product_id, product_description and product_family on clicking the lookup icon on portal form in a popup. On selection of a row from the popup it brings product_id into the portal form.

Is there a way to show on the portal form product_description + product_id + product_family. I still would like to send back product_id to the back end crm on submit.

Thanks for your help
