Hello, i'm quite new with MIT App Inventor and start getting stuck when creating my app.
So my problem is i had created my login form and all things works how it supposed to be, but there is a feature that i would like to add is the username not found notifier message. As you can see i've already made it, but it didn't work, so i hope you can give me some suggestion.
Ps: Sorry about my grammar. I'm still learning english.
