Search form not working

When I try and use my search form it tries to add the url of the current page to te search only it seems to add the directory name into it even though I use a subdomain. I don’t get this error with anything else.

It should be a URL like:

http://mahblog.neo-ilove.com/index.php?s=happy&submit=Search

Instead I get a URL like this:

http://mahblog.neo-ilove.com/wordpress/index.php?s=happy&submit=Search

Which brings up the error. How do I change what the SELF ‘tag’ (if that’s what you call it) brings up.

Many thanks
