Warning Layer and Text Variable
1. How to determine the text variable as shown below. I don't know when the text variable is V2, V3 or V7 ...?
2. As a warning layer: If the user has not finished the exercise, he / she cannot submit the lesson. I have enabled the submit button to be: if the space is empty, the warning layer is displayed. However, some of my other slides when clicking submit do not show warning.
I have attached the project below, the first slide: warning my layer works normally but for the second slide, warning layer does not work when I click submit
