So I added a bunch of form validation stuff to the submitCompany.html page using parsley.js. I was unable to test it as I wasn't able to get your Tornado server running locally--it kept saying "no module named tornado.escape" even though I installed Tornado via PIP. I might need you to send me some quick instructions on how to run the app locally. Anyway, see if you can merge these changes and run it and see if the form validation stuff works? If so, I can add it to the other pages as well.
