Ok so I am a complete novice and I desperately need help.

I have been setting up my site http://www.boothmadness.co.uk and somehow I have managed to make all the text from the body of my blog appear in the sidebar. Please please please can someone help me to delete this?

I have tried everything I can think of and I am stuck!!!
