I'm rebuilding this a website for a local club and I have encountered some problems with IE. The site looks good in Firefox (except the navigation bar). When I visit in IE, the right column overlaps the left column?

Also I cannot figure out how to center the navigation bar in the left column in firefox?

Any help is appreciated!!
