I believe I have a basic idea, but wix has been messing up on me so much this week that not sure if using correctly or not, as can not get the site to work consistently to really know or not.
I am assuming that by creating a dynamic page with ID as the selected field it created a page that matches only ID. What I did not know that it does not really create a author only access....you have to create a dataset with a filter for owner. But what does that ID field really do? Same with adding field of "title", etc, etc. What is it really doing?
