Add a feature to a php script

I own a specialized dimesale php script that needs an additional feature.? The script manages several dimesales from one database.? I just hired someone here on rentacoder to get it working, but once it was working, I realized a flaw in my logic on the original project.? Once the script goes through paypal, it is returned to a page that, when it is called, modifies the database.? But then it stops, and it needs to automatically redirect to a download page that is specified in the settings file.? Basically, the main script needs one more feature where the administrator can place the "download" page in a variable via the current GUI, so that the script can come from paypal to the return address, and then redirect to the download page that is in the database. If you would like to see the script, you can see a live version of it at [login to view URL] password is insertpasswordhere Click on the "List Products" tab and then click on "edit".? Then type a "1" in the box (if possible, I would like the "edit" link to go directly to the appropriate product rather than have this extra step, too) and go to that product.? You will see some URLs that I have typed in.? I need one more URL to be listed there....the URL of the download page. So that's it...those? 3 items.? 1.? Get rid of that extra step on the "edit" link, 2.? add that redirection code to the [login to view URL] file, and then 3.? place that extra download URL box in the [login to view URL] script. Please ask questions if this is not clear to you.? This should be an easy job for someone who knows what they are doing.
