Comma in Post Counts Causing trouble

[Gutspiller]

I'm hoping somebody can help me with a problem I'm having. In my forum I included a comma in post counts so that instead of saying a post count of 50000 it would show up as 50,000. The problem is, is that sometimes it will not show the last digit so a post count of 50,000 would show up as 50,00 Can somebody help me fix this probem? Here are the instructions I used to get the comma in the post counts:

In admin/functions.php:
Look for:


code:  
//highlight words for search engine

 



Add the following directly above it:

code:  
if($post[posts] >= 1000) {
  $left = floor($post[posts] / 1000);
  $right = $post[posts] % 1000;
  $post[posts] = "$left".","."$right";
}

Can somebody tell me if the intructions are messed up or what I can do to fix this problem? I will remove the comma before I put up with this problem any longer, but I was hoping somebody might be able to help me get the commas to work correctly.

Thanks in advance if somebody can help me.
