Hello all, my first post. The FAQs and forums have kept me going pretty well, but now I'm stalled.

I have a need to prefill a text attribute with a parameter passed in on the url of the product_info page.

My customer sells photographs from their historical archives collection. With over 50,000 photographs, having a separate product for each photograph is unrealistic, so I have one Photograph product with an attribute to specify the photo number they want to purchase. The photographs can be searched and viewed from their web site, and I would like a user to be able to purchase a photo by linking directly to the product_info page at http://chessieshop.tracefork.com/ind...oducts_id=1860 with the Photo Number attribute prefilled for them with the photo number they were viewing.

So I am looking for hints on what zen code do I need to change to allow my zen-cart to accept something like "http://chessieshop.tracefork.com/index.php?main_page=product_info&cPath=46&products_id=1860&PhotoNumber=12345.678 "

and then prefill the Photo Number attribute with 12345.678

Thanks,
Lars
