You connect two sections in the registration form builder by dragging a section onto the form and linking its node to the other sections. Every section must be connected for the form to flow from one section to the next.
In the sidebar of the form builder. Drag a section from the sidebar and drop it onto the form.
Make sure each section's node is connected to the other sections in the form, so every section is part of the registration flow.
Your account is using the Classic Form Builder. Turn on Switch Form Builder Interface to use the Node Builder. See How to Configure Ticketing and Registration Settings in Eventify.
