dataset 1 is connected to a collection called ‘Viewers’ with custom use permissions allowing anyone to read, create, update, delete content.
Not sure what you mean by how is the current item set before arriving at this page.
Before, it was on the same page but it pulled the First and Last names of the currently logged in user, which I used to show in the text element. Now it just brings up the first entry from the collection ‘Viewers’
