Question: How to open door when all variables are true?

what i have is there at the link, idk why i cant upload a screenshot.
What im trying to do is when all 4 variables come back true, the door will open on its own. The door just does nothing. Any thoughts on whats wrong or a different way to do it?

You have nothing to execute your code. You need an event to fire that entire chain of functions. You should also replace your ‘Can Open Door’ with a branch.
