Hello Ofentse,
this indicates that a formula is not correct. Please check the database by validating it (right-click on the database when it is open), it will then show the processes where the formulas are incorrect (which can happen due to mis-spelled parameters or so).
Best wishes,
Andreas

Hi Andreas
I validated the database and it shows that everything is okay.
