Can you add some screen shots here for us to help
It does not matter if I do the step or the app does. Same error when tying an entity to the button. Below are the screen shots
I let the app do the steps as shown
The app does not know which entity and it than errors. From Here I do not know the next steps to go on and I need to process per the introductory steps so I can complete assignment
This happens everytime I try to do this.
