floatval is a standard PHP function:
http://www.php.net/floatval
what version of PHP are you running? if it's older than 4.2.0, that's why you're getting this error.

your version of PHP does not support the floatval command.
either upgrade (good idea, since it's also very buggy), or use:
(float)<var> instead of floatval(<var>)

i had the same problem (php 4.1.2) , but the function float doesn't work, so i copied this function from www.php.net/floatval

Code: › function floatval($strValue) {
$floatValue = ereg_replace("(^[0-9]*)(\\.|,)([0-9]*)(.*)", "\\1.\\3", $strValue);
if (!is_numeric($floatValue)) $floatValue = ereg_replace("(^[0-9]*)(.*)", "\\1", $strValue);
if (!is_numeric($floatValue)) $floatValue = 0;
return $floatValue;
}

put it above the other function and everything works perfect!
