Need help for a basic app

[Alfred]

Dear app friends,

I want to make an app with app inventor 2, but I don’t really know how to arrange the blocks. Here is the concept of the app:

1. There is a page with several proposals (text), and a button that follows each of these proposals.
2. When you click on a button, you arrive on another page with new proposals and new buttons that go with them.
3. Then, one after the other, we arrive at a final page which is the result of the path taken with the buttons.

If you want, it is an interactive form where you filter the search more and more, choosing proposals, to arrive at a final solution.

In fact, all I have to do is create a lot of pages and then link them together.

How do you arrange the blocks to have a screen, a button on this screen that sends us to a new screen when we click on it?

Thank you for your answer, Alfred.

If you decided to use different screens, then you should switch them correctly, else you …

Don’t use multiple screens for this, just use List Pickers or List Views and reload them after each choice from the lists.
