hey guys wonder if you can help me im not a coder i admit that but i can find my way around most things even if it takes me days to figure out, this one is on the verge of beating me though.

My forum Webmaster Marketplace - Qdoos, ive installed a right coloum on the right funnily enough, its ok on the home page and category pages but in the post pages it jumps out of the template. could some one please help me ? ill give you admin access to do it etc , im sure its very simple but i just cant see it.

Thanks guys
