It is my first attempt with DriveworksXpress. I want to suppres/unsuppress a part if a checkbox is check or not, something really easy, but I don't know why Driveworksxpress always says my rule is invalid. I copy exactly the same rule as in the helper guide, but with my variables and it doesn't work. Do you have any idea what is my mistake ? Here is a picture of my rule, where BIN is my variable (checkbox).
