CSS / Javascript woes

Alright, so here’s my problem(s)! I’ve been fooling around with CSS to possible make a new sitey for myself, but it doesn’t seem to be panning out too smoothly. My site is located at:

http://dividemysky.com/test/test.htm

First of all for some reason in IE 6 on windows, the Javascript on Line 13 is giving me an undefined error, but Im not getting that error on any other browsers. Even more frustrating is that the page still works on IE 6, despite getting the error! How can I get rid of it!

A second picky thing that the page is doing is that my left most DIV (with the navigation in it) will flow to the bottom of the parent DIV in both IE and Safari on Mac, but in widows I can’t get it to go all the way to the bottom (as well as the fact that the list margins become HUGE in this browser). What am I doing wrong?!

Desperatly Yours -
