Please use code tags for posting code (# or <> button in the editor toolbar). You should also ensure that your posts have a meaningful title, not just 'Help me'.

Your HTML is very broken. Put your DIVs in the body, not the head.

If that doesn't help, just use a debugger (Firebug or Chrome Developer Tools are good) to inspect the stacktrace and figure out what el should have been when it was null.
