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/...
Brenda,
The default value (that is set when you create the variable) really just determines the initial value of the variable before any other action changes it. It doesn't "restore" the variable to this value in any way after the value is changed, so the default value is only useful for setting initial conditions when the app first starts.
