Hi I am trying to reference a page list property in a section. I have a page list property called 'Entities' which is being sourced by a data type that has (FirstName,LastName SSN). I created a section and added text inputs for a user to enter in their first name/last name etc. So I referenced the property on the text input as '.Entities.FirstName' so the user can enter in their first name. However, it does not work. When I save and run it does not allow me to enter any data. Upon further research I got this error:

"

The reference .Entities.FirstName is not valid. Reason: list property 'Entities' must have an index

I also have tried with index '.Entities.FirstName(1) or () to no avail

Does anyone know the issue in how to resolve this? Thank you.
