I'm afraid I don't understand. We need a lot more information to know what you are doing. Specifically, we need to know four things:

1. What are you trying to do?
2. How you are trying to do it?
3. What results do you expect?
4. What results are you getting?

In short, we need to know enough about what you're doing and how it's failing so we can reproduce your problem. You understand your problem well enough that perhaps you're simply assuming too much knowledge on our part. Assume that we know nothing (except Perl), start from the beginning, and explain what's going on.
