	Whoa, wait a second - if you have sizes of 7", 7 1/2", etc, you will find
that whenever someone orders 7 1/2" their order will mutate into 7".

	You need to state your sizes in the products.asc like this:

	2,1,10=1/0,20=2/0,30=3/0,40=4/0,50=5/0

	So the select field will show "3/0", but the value will be "30"...  the
loop increment tag will then work correctly.
