Interactive map (non Flash) hover problem

I've followed this tutorial - http://www.netzgesta.de/mapper/ to create a state map of USA which you can see here - http://www.teamworksdesign.com/clients/neurosign/contact/alabama/

I downloaded the source files and got it all working locally then uploaded all the files to the link above. It's almost working but the hover doesn't seem to work when you hover over each state. I had this working locally but cannot work out why it's not working online.

One cause may be that Wordpress (that's what the site is built on) is blocking something along the way.

Can anyone help?

UPDATE: It's blatantly something clashing with Wordpress as it worked locally, does anyone have any 开发者_Python百科idea's of how to fix it?

Make sure that you're linking correctly to your js files. Also, your CMS might not like $ symbols - try swapping them all for jQuery instead of the ref symbol... 90% of the time that does it!

According to firebug's net tab the following files are not found (404): maputil.js, mapper.js, wz_jsgraphics.js, cvi_tip_lib.js.
