[wlug] javascript

hi there all is anyone able to help me out with a bit of javascript code? On my webpage:gmorrissey.kol.co.nz I have a page called page_template. I have only uploaded the red and black images for the first two buttons (a blue and a red button for mouseover). I dont think I have quite got the code right as the buttons arent changing colour on mouseover. I had an online script that I used as a template, I seemed to have gone awry for some reason. Any tips appreciated. Glenn.
