Re: there must be better way to handle "Null" undefined variables

For future reference, Fred, please only include the relevant code, not the entire script.

It's not an OS thing at all. You can change php.ini on the offending system to this: error_reporting = E_ALL | ~E_NOTICE ; Note that the | is the pipe character. Preferably, though, the variable on line 198 should be defined. It doesn't absolutely *NEED* to be, but good coding standards beg that you do.
