Variabe != Value???

Hi all, I just found a very strange thing inside my code. I tried to make a standard GET link like: <a href=\"".$PHP_SELF."?product_list&action=editproduct&product_id=0001>EDIT</a> which should work right?.... WRONG!!!! when I try to recognize the "$action" variable it just goes through without reading it... I checked my code for hours and every IF and ELSEIF look fine. Now, if I take the "$action" variable away and justleaves "editproduct", the code listen ok... Any ideas? maybe a reserved variable?
