I have a question about attribute that may have a simple answer, I've got a feeling I'm over thinking it.

I looking for a way of display a particular product (lets say air filter for example), that is available for a large range of motorbikes, each with its own product number.

It would be time consuming to list each one separately and to create attribute for each one would again, be too time consuming.

The obvious solution (I think) is to list the filters, with there individual codes on a single product description page and have the customer look up their bike and enter the correct code in a zen text field attribute.

To avoid customers entering the wrong code I was wondering if their is a way I could put a link the product code number (on the product description), so when a customer clicks it, it would automatically enter the correct code into the text field.

I have seen this done but can't remember where, I'm thinking Ajax would be good for this?

Any suggestions welcome
