What am I doing wrong?

28/03/2008, 03h09

I have the calculator running smoothly on my 'Actual Webpage', but i wanted to
know how it actually worked. So i started a new document and threw together a
small 'form'.

The HTML code you see below will appear as a small box/table thing, with 2
checkboxes. when you click on the checkboxes, the total is meant to add up in
the 'total box'...but it doesnt seem to want to work.

So, could someone tell me what im doing wrong. Im not a javascript pro, so be
kind.
Thanks
