The <c> block looks like an artifact from his HTML, if that's what you mean--it shouldn't show up in your code...
That is, he was saying if you aren't going to use forward slashes to delimit your regex, then you need to prefix it with m:
if ($blah =~ m#regex here#options here)
instead of the usual $blah =~ /regex here/options here
or what have you. (In your post, the regex doesn't appear to start with a forward slash.)
I'm a peripheral visionary... I can see into the future, but just way off to the side.
