IFrame Issue - IE6

hey people has anyone got an idea of how i can get round this…

if you goto www.onsetcold.com/index1.htm

then preview in firefox and then preview in ie… you will notice ie has 2 scrollbarrs were as firefox has one?.. the css inside the iframe is set at something like 300px width so there shouldnt be a second scrollbar?.. basically the firefox version is what i want for ie…

help?

bit of a deadline on this for me as its needs to be up next week for when there in terrorizer mag… so any help would be appreciated!
