    Yes/no parameters

    I had two parameters that i was controlling with "not(**)" parameter. Worked fantastic...
    Now i'm trying to add a third one and getting that to control the other 2.
    So turn on the "Ex" yes/no parameter and the other two turn off.
    But what i'm really after is a formula that will, when i click one of the three it turns off two, then when i click another one it turns the other two off, etc.
    Make scene?? I've attached a screenshot of the family parameters.

    i'm really not great at these family's. I can build them easily but the formulas really aren't my strong point. If anyone could shed a light on what to do that be great.

    Once you add the formula to the checkbox with a yes/no you loose the ability to to use it

    A common workflow flow to get around this has been to create an integer value parameter which lets the use choose the option with an integer value, you can then have you visibility yes/no paramter read the Value integer "Value=1" for option 1 etc

    It is a bit messy but can work.

    My first choice would be to use types instead, I would only go this route if every instance is going to have a different combination of options checked
