I can see a few problems here Lisa.

You need to DELETE the existing trigger that says 'Jump to slide Next Slide When the user clicks or swipes Next". Its doing nothing for us.

Secondly, your "Set state of Next Button to Normal" trigger is using the same Asset in all three conditions:
"If the state of Click to close = Visited
and the state of Click to close = Visited
and the state of Click to close = Visited

This should have three different assets mentioned here, not all the same one.

Finally, I even if you had the conditions correct, I doubt it would work, because you are trying to set the state of the Next button to NORMAL "when the user clicks or swipes" but remember, you already set the Next button to DISABLED so its impossible to click or swipe it!

So here is something you could try.

Forget changing the Next button to disabled. Delete that trigger.

Also delete the "Set state of Next Button to Normal" trigger that we just spoke about.

Instead, add a new trigger that says:
"Jump to slide next slide
When the user clicks or swipes Next
If the state of <Asset 1> = Visited
and the state of <Asset 2> = Visited
and the state of <Asset 3> = Visited"

That should work :)

Let me know how you get on.
