I started out by building the basics for the workflow, before turning it into an app.
In the end it came up looking like this:The Workflow
From within the Alteryx Designer you can then run the App, and when I do, it ended up looking like this:The App
And the result (depending on the answers) pretty much looks the same as in the provided AppThe Result
I am happy though, that I have previously watched the Analytic App Development for Intermediate Users Live Training
since it gives some great insight not only in how to build applications but also how to debug them 👍
