Help desperately needed! IE/firefox problems.

Hi everyone!!

I own a website called www.comparebookies.com. I broke it the other day and asked a coder to see if they could fix it. They changed loads of things in the site and have left it with some problems.

Everything seems to be fine in Google Chrome but there are some noticable issues in IE/Firefox - missing buttons, red boxes around the logo, etc.

Can anyone take a look at it and tell me what might be causing the problem? I need to get it sorted out asap as I am missing out on revenue associate with the World Cup!

Any responses are very much appreciated!!

There are a lot of error in your markup, see http://validator.w3.org/check?uri=http%3A%2F%2Fwww.comparebookies.com%2F&charset=%28detect+automatically%29&doctype=Inline&group=0. Try to fix them all first.

Thanks for the reply! Is there any error in particular that I can solve in wordpress that might be causing the buttons/word press headers not to show and the main logo to have a box around it?

These are the main problems and am desperate to get them sorted.

Thanks again.
