User defined function problem

Hey Guys and Gals, I am having a small problem with a user defined function, I placed it in a config file and it works as expected, but the problem seems to arise only when I try to use my login script for a members area I am redeveloping. The error message that comes up is the following: Fatal error: Cannot redeclare clean_sql() (previously declared in C:\Apache2\htdocs\braille\config.php:94) in C:\Apache2\htdocs\braille\config.php on line 108 The problem is its claiming that I am trying to redeclare the function in the config file when there is only the original function. I checked in other area's where this config file is being used and I do not get this error. Nor am I including other files that have the config included in them. The problem is only in my login script. If anyone can give me a little insight into this error I would be greatly appreciated. Best Regards, Steve
