CountZero

Ok, I admit I made a mistake when saying the output was the same.. Sorry 'bout that, but that's how we learn, right? After testing that piece of code again, with '=', I got the output I desired. But when tested with 'eq', I got the following message as well as an empty output:

Useless use of String eq in void context
[download]

I also got this error message for every single line of my code:

Use of uninitialized value in String eq
[download]

So what's that all about then? :s And how can I correct it by using 'eq' instead of '=' then?
