Product Sets and PHP script inside product pages

[bangsters]

Hi.

has anyone been able to implement product sets into zencart? I need something that will allow me to create a product based on different individual products. best example is a poker chip set with different colored chips. the chips themselves are indivual products, and the set is a different prodcut as well. the set should allow to, say 500 chip set, only allow 500 combinations of the different chips.

Has anyone made something like this? module perhaps?

Also, how can I put php coding directly in the products? If I try to put scripting in the product description it gets ignored.

Please advice.

Thanks
