I have a new design I'm just finishing up on http://www.get2sammyb.co.uk but I have a small error in my design. The flaw is that the main box containing all the content should be in the centre - however I ahve tried to do this in a number have way but it has always resulted in the text inside the content box also being centred - which is not what I want.

How can I solve this problem?

Thanks in advance.
