Could you perhaps share a screenshot of what you have got now?
That should make it easier for us to find out the problem and provide a solution.
In the first image i created a data view and then in the second image i did a data view first with “Training even” and then a list view with “…../registration”
I then want to create a new page feeding from the “Add” button but it doesn’t allow me to select the Registration entity. Hope this helps
