So, I see that others have had a similar problem and it does not look like anyone has solved it based on my research on the topic. It may just be a bug that has not yet been resolved.
I have a simple form that I have created with user input boxes and a submit button. I used the Connect to Data icon to connect each element to the same dataset.
But here's the issue...I prepopulated three of the elements with user email, first, and last names.
When I use the button to submit the form to the dataset, only the fields that have been entered by hand are being saved...none of the prepopulated fields save to the database.
