Greeting people, I have been using the links 2 for a while now, but i seem to have picked up a strange error..

I get this when i try and run the nph-build.cgi script:

CGI ERROR
==========================================
Error Message : fatal error: Illegal division by zero at nph-build.cgi line 432, line 412.

Script Location : nph-build.cgi
Perl Version : 5.006

Form Variables

I have no idea whats causing it, i have tried re-uploading the original of the script, but it made no diffrence, i even reinstalled the whole thing, but i get the same error, and ideas why??
