Re: form validation

<?php

        if( $my_form_var % 50 ){
                echo "$my_form_var is not a multiple of 50!";
        }

?> the % is the modulus operator meaning it returns the remainder of a division operation. If the number is divisible by 50 the remainder is 0 ( aka false for the if statement ) other wise it is not 0 ( aka true ) http://www.php.net/manual/nl/language.operators.php morgan At 04:42 PM 4/12/2001, you wrote:
