In the form 'TestForm' I have two fields: 'Player_Name' and 'Player_Entity'. Each Player can have multiple Entities. They are entered in another form. The field on the 'frmPlayer_Entity' form containing the name of the Player is also called 'Player_Name'.

Now in TestForm I tried to make Player_Entity a lookup field with the criteria 'Player_Name == input.Player_Name' (to get only the Entities of the entered Player in the dropdown) and I get the error message 'Variable 'this' is not declared'.

Is it not possible to state lookup criterias with simple field information on the same form? Or am I missing something here?

Thanks, Filip
