Hello, everyone,

i had the idea to build a login screen with a disabled button if the mail/password is not correct
Can someone find my error or explain it to someone with almost 0 experience in programming what I have to change?

Important is that part: [disabled]= “false " when E-Mail ="test@dhbw.de” & Passwort =“ITV2020” else [disabled]=“true”

So you can press the button and get to the next page if the mail and the Passwort are Right. Just for your understanding.
Thanks :wink:
