Hi Jen,
Take that DHTML code out of the template you currently have it in and move it into the /customer/home.tpl file. You'll see the <head> and </head> tags in there.
You might also consider making a new .tpl file (maybe call it menus.tpl) and putting an include statement in the home.tpl file calling up the menus.tpl file. This way you will have all that DHTML code in one file rather than having it clutter up your home.tpl file.
Hope that was clear!
