RE: [PHP-WIN] Windows2000 OS - PHP 4.x - Warning: Undefined varia ble:

What's happening is if you send the form with that box empty, there is no data in the variable you are trying to trim. To fix this, you could do something like this: if ( isset ( $SearchValue ) ) { $strSearchValue = trim($SearchValue); } This way, the variable will be skipped if there is nothing inputted.
