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/...
But if that was the case, then surely you'd have this issue when having to us numerical entry, e.g. for calcs etc. If you still want to collect numbers but don't need to calc them then I guess you're okay.
