Using variables to change states across different slides

Two ideas:

Visited is a built-in state with built in triggers. An object with a visited state changes to Visited when the object is clicked. If you write a trigger to do that, the built-in actions may be offended, and refuse to work . If you want to change the state of that object with a trigger, then you need to use a custom state with a different name.

Also, there is a possibility that Oval 1 is on a different slide than the one that changes HOME. In that case, this trigger won't hear HOME change, because variable changes are heard only on the slide where they change. If the trigger hears the change, it can't change a state on a different slide.

So, change the name of the state, and be sure HOME is changed on the slide where Oval 1 is.
