Hey everyone. Having a problem I was hoping someone could help me with. I am fairly new to php (i’ve done some forms and interactive database work) and can’t seem to get this one right. I am adding a couple options (one at a time since i’m still stuck on the first one) to show up on a cart page (size color etc). I have the variable going between the two pages as I can echo it out on the cart page but for some reason I can’t get it to output what variable they choose; in this instance it’s size. I will put the cart php here and if someone more knowledgeable has a moment to peruse it and point out where my error(s) are I would be so grateful as I have been working on this project 10 months (I have a developmental learning disability) and still don’t have a working final product.
