I'm not seeing what is causing this: (Fatal error: Cannot redeclare shopdisplay() (previously declared in /home/katarra/public_html/shops.php:11)in /home/katarra/public_html/shops.php on line 21) error...

 

Any help would be appreciated! (This probably isn't the only error, but it's the one that's stopping me from finding the others)

 

Thanks!

You are including the posted code more than once. You either have an include/require statement for that file inside of a loop or in more than one other file that is being included, or one of the files you are including in that file is also including that file.

LOL, I was just looking through the remainder of the code, and it is including itself -

 

	if ($do[0] == "buy") { include('shops.php'); buy(); }
elseif ($do[0] == "buy2") { include('shops.php'); buy2($do[1]); }
elseif ($do[0] == "buy3") { include('shops.php'); buy3($do[1]); }
elseif ($do[0] == "sell") { include('shops.php'); sell(); }

 

If you are already running the code on that page, why are you including it? It already exists.
