(You can change this in properties.) Second, select and highlight the secondary parameter, go to properties, and select “Chain Actions” = yes. Third, go to the action of your primary parameter and right-click it. Select “action selection set” > “modify selection set.” Add just the parameter of your secondary chained parameter to your selection set. Don’t add any of the drawing objects. Now test your block. When you activate the grip for your primary parameter it should automatically activate the secondary parameter.
