Whether it's what he actually wants is something else. He asks to replace the comma with a zero and a comma (actually, prepend a zero), not replace the comma with a zero, which is what your "correct" script does. Make the last line: $str = "0" . $str; and it'll do what is asked. ===== Mark Weinstock mark_weinstock@yahoo.com *************************************** You can't demand something as a "right" unless you are willing to fight to death to defend everyone else's right to the same thing. *************************************** __________________________________ Do you Yahoo!?
