as per my name, all this is really new to me. I am following "Build your own website the right way" and just attempted my first ever navigation div on my mock up home page. When I click the link it tells me the file cannot be found. I have checked my markup 3 times and just can't figure it out. I did download Firefox on my windows vista- that is the only major change I have made to the computer.

anyone?!?!
