Doesn't seem to be working for me in Chrome on Android. I submit the form, the page goes blank, and nothing else happens. Also, a suggestion, the fields rendering in a random order will be very confusing to someone if they are going to be using this multiple times in a row to compare pricing of different EC2 specs. I was very confused when region was at the very bottom the first time I tried to submit the form, then at the very top the second time.
