Percent of a Number

[Anon]

I'm trying to display 35% of a number using the code below. It worked fine until the number reached over 1,000. Am I missing something simple? Thanks.

<?php $perc=($total * .35);
$perc=number_format($perc,"2",".","thousands_sep");
echo ("$$perc"); ?>

I dunno why it doesn't work on your computer but for me it seem to work whatever the number I put in...

Wacky

Could it have anything to do with a comma being inserted somehow? If this is it, is there a way to strip a number of a comma first and then perform the multiplication? Thanks!
