"this is what Im trying to do but in vain"

Provide: sample input, expected output, the code you're trying, a description of what you're having problems with, your actual output and any warning or error messages (all described in "How do I post a question effectively?"). Also, improve the readability of your code with indentation (described in perlstyle).

If you do all this, I'll be happy to provide further assistance.
