Is there a way to check that the user has entered a valid number in a data entry field?
I want to prevent the user from seeing a NaN entry when the calculation takes place - for example when they delete the default value and don't enter a valid alternative.

Hi Martin,
This has been a common question and right now would need to be a feature request.
Here are two threads that discuss some workarounds, and here is another one.
