Hi, SNS.
Thank you for reaching out, and for sharing the screenshot!
When using Built-in states, such as Visited, there's no need to create a trigger to change the object into that state. The logic is all done by Storyline for you.
It looks like you created a custom state called "vvisited" instead. Is there a reason why you're not using the built-in one?
Try removing the highlighted triggers below, and changing the condition for the continue button to "when all the rectangles are visited":
Let me know if this works!
