Save button not working

I have an app where the save button is not functioning, meaning when it is clicked nothing discernible happens on screen (and obviously the field information in the app is not saved). The cancel button works and closes out the app record. This happens with a new record or trying to edit/update an existing record. There are no warnings popping up about too many field, etc either. 

Hello Michael!

To clarify, some custom JS is set up in this app, correct?

If so, you could try to debug and see if there is an error popping up on the developer console. If something is wrong with the JS, you should see some error here.

If there is an error, can you tell me in detail?

Thank you
