Another question as I got through these initial tutorial videos. The videos want me to create a workflow where when you press the sign-up button, my pop-up shows up. However, when I try to create the workflow, the option of using my pop-up is not available. See below:
I suspect the login/reg form in the tutorial is a “reusable element”. These elements are self contained and (generally) cannot be accessed from outside. So, the workflow to register the user needs to be done inside the reusable element rather than on the main page.
Click on the top left to see a list of reusable elements in your page, that will take you to the edit screen for the element.
