forum with fixed width - can't display a div next to the forum

[StarBuG]

Hello

I have a problem.
I want to display a leaderboard above the forum and a skysraper on the right side next to the forum so that it adds to a hockey stick AD.
My forum has a fixed width of 1024px and is centered.

The problem is that I can't get a DIV container next the the forum.
I set the container above the above_body div but it displays above the forum not next to it.

Any help would be much appreciated
