How to manage Alphanumeric variables
Posted: November 26th, 2016, 7:37 pm
I have a matter.
I created an alpha on which I would like to make a restriction on it such that it will not be possible to enter both numbers and letters. I would like when it enter both numbers and letters an error message appears.
I would like it will be enter either only number or only letter
Thanks to help me to solve it
