Dynamic Drop Down Lists

I've got 3 drop down lists. The first one changes what appears in the
second two.
For some reason the code below is only deciding to show me the first two
items that appear in the two drop down lists in question. So, this leads me
to believe the problem shuld be quite simple to solve! but i've been stuck
on it for a couple of hours now!

If someone could help me out here I'd be extremely extremely greatful!!!!
