texte = Let me throw an idea out, albeit a little bit of debugging theory. It might not apply at all but at least it's an idea for troubleshooting. Some time in the past 6 months one of my sites decided to "suddenly" stop adding to the cart correctly. I believe it happen to me right after I upgraded my 3 trade show notebooks to IE7. So not only did my Dreamweaver 8 break because of IE7, but it apparently my add to cart code just didn't want to work 100% of the time any more. I remember debugging it for days. In the end it turned out that a new [include] file I added was occasionally redirecting my process before hitting the "add to cart" code block. I also seem to remember it was "old" code, so it could have been there since 4.5, even though I've rewritten a lot since upgrading to 6.x. Basically this is what I'm saying: Take a good look at your code. Maybe you didn't change the Add to Cart code at all. But did you change any other code that processes before it? In my case I was having trouble in an [include] that was called by another [include] that was processing before the add to cart. So try breaking it down systematically, because from an engineering point of view there is a reason for it to work sometimes and not others. It's a computer and no matter how we want to talk about ghosts in the machine, in the end it's always going to process to a ONE or a ZERO. You just need to isolate things differently until you find where that ZERO is being processed instead of a ONE. Oh and as a little point of interest while I was debugging my issue I went from not adding to cart to always adding 2 of the same items to the cart. So just pay attention to your [include] files because they can really screw you up and create unexpected loops. Sorry act like a college professor and be all cryptic with programming "theory", but like I said, I just figured I should throw this out there.
