I'm grabbing a link from HTML and fixing it to take out the /../ and replace it with the absolute address. Here's the regex part of the code and some example variables.

$base_url =
"http://www.something.com/angels/devils";
$base_url =~ s!/[^/]*?$!!; #strip off the subdirectory
print "$base_url \n";
$address =
"http://www.something.com/angels/devils/../faries/";
$address =~ s!.*/\.\./(.*)!$base_url/$1!eg;
### stick this in &grabLinks ###
print "$address \n";

Output is:

Illegal division by zero at line 14.    #it's line 7 here...

I assume I'm doing something wrong with my formatting, but I can't figure it out. I tried adding {} brackets around the variable names but it wasn't working. Thanx for your help.
