Diagnoses

Errors appearing on the rules prevent from saving a form but the rules in error cannot be solved/deleted. This is initially two errors upon the form which ar referencing controls upon a view within a subform not being configured correctly.

 

Resolution

Recreating the rule's for the controls upon the view and making sure they have been correctly configured. Once these have been removed and recreated no errors should appear on the smartform.
