Is there anyway to redirect the list of value in the drop down box into a perl script?

Yes.

But I'm confused about how to redirect each entry in the list to the perlscript.

What exactly is confusing you?

This is really a HTML issue, and this should be enough of a hint to help you solve your problem.

How is it that you were able to diagnose this as a perl issue?

How to read the friendly manual is always interesting reading.
