T.J.,
Thank you for the extraordinary help - your script worked right off
the bat! The only thing I'm struggling with right now is the fact
that the cells I want to calculate are not just numbers but form
elements. So, cell.innerHTML is something like input id=grade1
value=20 instead of 20.
Again, brilliant help on everything guys!
I worked on this thing for quite a while last night and eventually got
it to work in a round-about sort-of way. I used something like
cell.getFirstChild().getSibling().value; a really ugly hack. I ended
up making the changes as suggested by T.J. and it
