CSS Problem in Topics

I'm having some trouble getting my "Topics" section to look right in Firefox and IE at the same time.

When I'm editing the template on blogspot, the Topics look fine. However, once they are published, Firefox shows "Bluray" and "DS" doing the horizontal mambo. In IE, the lists don't line up, but IE is IE, so I'm not too concerned about it.

If anyone has suggestions, please hit me up.

Edit 06/23/2006: I had mispelled the word "style" on one of my div atrributes. That changed everything. IE looks fine now, but in Firefox, instead of Bluray being pushed down into DS, DS is being pushed up into Bluray! Weird. Again, the "preview" from Blogger looks fine, just not the actual result.
