[thelist] Javascript orderform speed issue

I've got a large order form that uses script to update the subtotal
automatically as soon as you enter a quantity. The page itself is pretty
large - about 1050 products in about 11 tables. I'm working on slimming
down that code. But the problem I have is the speed of updating the page
total. Every time someone enters a number in the quantity field, I need to
loop through all 1050 fields to update the page total. In Firefox it's
pretty really zippy, but in IE6/Win it's incredibly slow. I'm guessing on
older /slower PCs it's almost unusable. I've optimized the Javascript as
much as I can, but I'm wondering if anyone can explain why it's radically
slower in IE, or suggest a faster way to do this?
You can see the form here: http://memoryboxco.com/orderform.htm
Thanks,
Rory
