Your guess is most likely correct.
From what I saw after looking at your site real quick is that you have the path set to "/clear.gif" (no slash means current directory* with a slash means from the root of the domain). So it’s expecting the file to be here:
http://h199595wp.setupmyblog.com/clear.gif
And that returns a 404 not found error.
So, either:
A) Move clear.gif to the root of your website
or:
B) Change the javascript file and get rid of the ‘/" at path to clear.gif
==> Do not do both !
