Strange need

Hi all, I know this is not used a lot, but I'm building a site that will show up a some kinda strange content. It will have diferent tables inside diferent pages. Each table will show a diferent header with several colums showing diferent diameters of the products. The table header will not be created by PHP, so the colums diameters will not be handled or recordered using variables. The rows on the other hand, will show diferent products which will be obtained by PHP from a MySQL database. each product has several diameters and I need PHP to put a check sign (image made) under ceratin diameter colums for each product. The tables under I have that information are a products table, a diameters table and a relationship of 1:N table for the products - diameters. Can I make a PHP function that will recognize the HTML column content and compare it to the information collected from the DB relationships table, so it will know when to put a check sign in the column for that product? Thanks a lot on this one, Cesar Aracena caracena@infovia.com.ar Neuquen, Argentina
