When trying to build an expression (maximum effective date) on a view, I'm getting an error: "The expression cannot contain a field that is bound to the control.  Use a different field or do not use an expression."  I'm trying to follow the exercise in the Sales Orders tutoral.

Hi,


 


I have only encountered this error when I tried to create and add an expression that is referencing to the same control I am trying to add the expression to.


 


For example, you have an expression, you referenced a control called 'Data Label'. Then you tried to use that same expression in the same 'Data Label' control. Basically you cannot use that expression on the same control that the expression references. You can only use that expression on another control.


Please see below documentation on how to use expressions and how the expressions work:
