note 42640 added to function.abs

There's another problem in the below code. The correct function to see whether a value is an integer is is_int(), not int(), so the code should look like this: <?php if(!is_numeric($range))//checks for numeric input { $range=1; }//sets $range to integer 1 if input is anything other than a numeric value if(!is_int($range))//checks to make sure it is an integer (not decimal) { $range=int_val($range); }//if a decimal- sets $range to integer value $range=abs($range);//sets value to positive whole number ?> ---- Manual Page -- http://www.php.net/manual/en/function.abs.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42640 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42640&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42640&report=yes Search -- http://master.php.net/manage/user-notes.php
