formatting disaster

im having major problems with the formatting in this document. this document is used for my summer school notes, meaning the document is being edited from two different computers.

i started out using firefox betas, but now use ff3 on both machines. one machine runs vista sp1, the other uses xp sp3.

the easiest problem to check out is the font. the font WILL NOT CHANGE. im trying to have the entire document in "garamond" but i can't get it to work.

please help! i would love to share this document with anyone who can better figure out what is going on.

thanks,
patrick
