Re: Forms and While Loop

This code sets $CatID = 1 for every instance of the loop. What I am trying to do is modify MyCart (index.php) to produce a drop down list showing the various categories ($Cat). When a category is selected from the list, the form URL is set to include CA=$CatId and the UID, so for Category 1; $CatID=1, Category 2; $CatID=2, etc. The problem I have is that I can't figure out to get the <form action=.....> to pick up the $CatID variable, no matter what I have tried. If I put the <form action=......> inside the loop, I get multiple drop down boxes (no good). I hope this explains my problem a bit better.
