We can't help with what we can't see. Show us the code you are having trouble with or, even better, show us a small self contained script that demonstrates the issue. We will need a little data, the expected output and the actual output. See I know what I mean. Why don't you? for help with how to go about that.

Note that Perl is case sensitive so module names must generally be the correct case. Also note that your urgent problem is not our urgent problem, but the better you ask your question the quicker and better we will answer it. You will save a lot of time by spending some time getting your question and sample code right.
