Object state change tied to state change of another object

Thank you for your help, Sandeep! The trigger to change the state of the cover box to normal at the start of timeline is so that the user is blocked between every turn from selecting a white box without first selecting a blue box.

Your solution to change the state of the cover box when a blue box is clicked works well, although I'm still curious why the test slide works with the state change but not the main slide. Oh well, as long as it functions!

Thanks again!
