Saving User Input to Local Database

I am working on a simple app that includes the capability for a user to enter a test and a test result value (number). I have a page set up to do this with a field for each and a button using the SET action. I have the SET action making a local database value (Results.date) equal to the field value (var.date). When I run the preview on the computer and enter a value then click the button I receive a Syntex error and it indicates (Collection3907747=var.date). I don’t have that Collecyion listed anywhere in my app or compositor.

When I download a trial of the app on my phone and enter values in the fields and push buttons it does not give me an error but when I go to the display page for the database values it says there is no info to display.

Am I doing something wrong? I just want the user to be able to enter values, save them to the local database, and view the database info in a list form. Any help is appreciated.
