- You've posted as a reply to another Seeker's question. That's unhelpful to the other Seeker and unlikely to get you anything more than full explanation Corion has already provided.
- You don't seem to have bothered to read the suggestions about how to get the best value out of the Monastery. Please read and heed How do I post a question effectively?, On asking for help and at least sample PerlMonks FAQ.
- Most questions are better posed with (a minimal) code sample, error messages and/or warnings if any, and a narrative description of why what you've written doesn't satisfy your intent. (Obviously,that's not relevant here but the instructions at the text-entry box directing you to use <code>...code tags </code> around code and data, including error messages are on-target.)
The Monks are generous in offering help... but at least some of us are quite picky about two points: 'Use proper markup' and 'show some effort' (as in -- show your problem code. These points are discussed further in the recommended reading above.
