Can I prevent "NaN" from appearing in numerical entry?
Is there a way to do this? Am using conditions to handle which numbers ARE allowed and to display an error if invalid numbers are entered. But can't get it to stop letters etc from being entered/...
IIRC, switching to text entry (instead of numerical) means "NaN" no longer appears. At least I think that's the case seeing as I did this 3 months ago. If you only want the learner to enter numbers then you can use conditions to ensure this is the case.
