I think I follow your logic & it seems to me that you'd be better off using a TCheckBox and checking and assigning the .Checked property.
Your logic would then become:
Var   CheckBox1 : TCheckBox;begin  // assign Checkbox1.Checked somewhere (true or false)  Checkbox1.Checked := not Checkbox1.Checked;
... is this what you are trying to do? You are really just inverting the logic of the field, correct?
