Just make sure $variable has a value before you use it anywhere... plain and simple. If you're going to say: If($variable > 0) Make sure $variable has a value so you don't get the NOTICE message. As for the warnings about 'Undefined Index' that results from you using an index in an array that doesn't exist. Echo $_POST['foo'] When there is no key of 'foo' in the $_POST array. Check and see if a variable is set with isset() before you do anything with it. > I'm just looking for direction and the best solution.

Yep. > Or should I be taking the notices as just a notice to let me know and that > my code is fine? No, you shouldn't. Sure, it'll run fine at certain error_reporting levels, but it can also be fixed to run in any configuration of PHP. ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals.
