I need to use conditional attributes, hope this explains what I mean:

A product comes in a variety of sizes and colours however, not every colour is available in every size. Therefore if a customer selects a particular size, I only want the second attribute dropdown box to show the colours available for that size.

I can of course add the product sizes as separate products and only include the colours available for each. However, this means if a customer searches by manufacturer the results “appear” to show many duplicate products.

I noticed a master/slave product add on for osCommerce MS2 and was thinking of trying to install it, but from the forum they have had a few problems with it. The add on can be found here:

Any help would be appreciated.
