Simple PHP Tweaking/Coding

I have 20 pre-made template codes which I need to use for a certain background category. I've manged to show them in the textareas of this page [login to view URL], but I am not able to get them to change according to their proper background url in the textarea. Example, if I go to my page [login to view URL], the premade template codes in the textarea has to show argyle/[login to view URL], and if I go to [login to view URL], the premade codes should show argyle/2.gif. Right now if you copy the codes in the textareas, it would show "[login to view URL]", for all pages, instead of argyle/[login to view URL] , argyle/[login to view URL], argyle/[login to view URL] and etc. Please take a look at the following for better understanding: [login to view URL] [login to view URL] [login to view URL] Please do NOT apply if you do not roughly understand my above situation. I apologize if I'm not good at explaining it, I'm no php expert obviously. Kindly ask if not sure. Also I need this done by in the next 5 hours, do not apply if you are not able to start now and complete by 5 hours.
