Can someone help me with columns in IE7?

Hi everybody, making a site for a client of mine and while I have most of the site done, I can’t figure out what is happening to the layout in IE7. I tested the site in all the other popular browsers/version, but in IE7 the div that holds the navigation positions way far to the right and interferes with the content. Can anybody give me a hand with this?


Thanks in advance!

Don’t know if these are causing the problem, but they are not needed in #navcolumn {:
margin-left: auto;
margin-right: auto;
position: inherit;
