I have noticed that in some cases when I have a parameter driven by another parameter via a formula, the "driven" parameter is grayed out, and I choose what I want the "control" parameter to be.
But then other times I will set up a formula for a parameter, and I can edit both the "driven" and the "control" parameters. If I change one, the other one changes accordingly to make the formula work.
What can I do to sort of lock out the "driven" parameter, and make the only editable parameter be the "control" parameter?
