Any reason you took such a complex route? <?php if( strlen( $pw1 ) < 6 || !ereg( '[[:digit:]]', $pw1 ) || strlen( ereg_replace( '[^[:alpha:]]', '', $pw1 ) ) < 2 || strlen( ereg_replace( '[[:alnum:][:space:]]', '', $pw1 ) ) < 1 ) { // error message } ?> Cheers, Rob. -- ...........................................................
