Steps to reproduce

Add two conditions to a question which each have a different scenario.
Click the button to edit the scenario number. The field for the new scenarion number is empty.
Don't enter a number, just save.

Expected result

I would expect to not be able to submit the empty scenario number or have the field default to the current scenario number.
Also I would expect it to be a number input field.

Actual result

I can submit and get a database error.
