My Form has deleted additions I made while testing

Working with Selection Box and email responders.

It deleted all my additions...editing....and reverted back to origional.

WHY???????????

That's odd. Perhaps you have opened two tabs editing the same form and the older version autosaves itself? This is usually the cause of the problem. To restore it to the updated version with all your changes, you can use Revisions History. Guide: http://www.jotform.com/help/294-How-to-View-Form-Revision-History
