Hi!
I need to check the textBox input only for letters, avoiding numbers, spaces, accents and special characters.
If the input has numbers, spaces, accento or special characters, then call a notifier. some help, please?
Do you want to prevent the entry of anything other than letters?

Yeah, that's just what I want.
You can use this extension: App Inventor Extensions: Textbox | Pura Vida Apps
And whenever the content of the textbox changes, check if only letters in a list
Have a go, come back if you get stuck.
