Form Not Working

Hello -- 

My some how is not working now – cannot load it in to a web browser, or edit. I tried to make the form responsive for mobile via Designer & Preferences in the Editor.  Could that be the problem?  How can I fix this? 

Also -- Can I make the "Total Invoice Amount" field pre-populed as "$ 0.00" and in currency form?

Our sincere apologies. There was a problem with forms not showing any fields a few minutes ago but it should be working fine by now. Kindly recheck.

Thank you!
