/*
The below is the code for the validation. Right now - the only element not working is a validation for "select your size"
The page that it is validating is:
http://www2.dupont.com/Personal_Protection/en_US/sales_support/tyvekgarment.html

Can you please make this check that the site visitor has indicated at least one size? Thanks for your help
