it is not working

Please give more information. "It is not working" isn't very helpful. What happens? Do you get the wrong answer? Does the program not compile? Does the program crash? Give an error message? Or does your computer burst into flames?

If you're really calling your function like this:

counttags(I);
counttags(B);

[download]

then I expect you'd get a warning about barewords under use strict. If you go on to use:

counttags(+);
counttags(-);

[download]

Then I strongly suspect that it won't even compile (I haven't tried it). You probably want to rewrite these lines as:

counttags('I');
counttags('B');
counttags('+');
counttags('-');

[download]

And if that fixes it (which it won't for the reasons that rminner points out), then you should probably get into the habit of using use strict and use warnings in your programs.

Of course, this is all guesswork as I don't really have enough information to go on.
