Hi Good Day!
I facing same problem since an hour. Every time I put the gray blocks with variables PassengerNo next to [from BtnPassengerNo set Text to app PassengerNo].
I got error “There was a problem saving your changes”. How can I fix it? I just want to preview the PassengerNo to each Buttons and Labels the entered Variable called Passenger No. as simple as that. Thank your for your help.
