I'm quite lost on all this API stuff. It's way over my head. I'm hoping someone can post some simple PHP code for me. I need to do one simple thing.... **Change the quantity of an existing fixed price item using PHP**. Usually when people ask simple questions like this, they get directed to another page that gets me even more lost. I'm just looking for some simple code where I can enter the existing item number, a new quantity, and any authentication data ebay may need, and the qty will change. Can this be done? Thanks.
