Spenser,
the idea to source the fonction makes sense but since tho OP is a very
new beginner perhaps you could point him towards code showing him how
to do this?  I have never done this AFAIR, and while I suspect a few
minutes googling would show me how, it is likely to be more difficult
for a noobie.
