14218 Internal InputType ComboBox cannot have entries directly added to the combo
Cause
This error occurs if logic is attempting to add entries directly to the internal combo box attached to a table where the value of the inputType property of the table is Table.InputType_ComboBox. This combo box is automatically filled with the contents of the comboList property associated with the cell over which the combo box is placed. The text of the cell is used to select the entry in the combo. Using logic to add entries to the combo would cause disruption of this automatic process.
Action
Change your logic to avoid this error.
