States not changing when triggered

Hello!

I have images with three states: Normal, Hover (shadow added when user hovers over the image), and Visited (grayscales the image). The user is to click on each image which triggers the state to change to Visited, then jump to its corresponding slide. Once all images have their states changed to Visited, a button is to appear which allows the user to progress to the next slide. 

The problem is, the states of the images are not consistently changing to Visited. It works in Storyline when previewing, but once published to Review and Rise it does not work as intended. 

Any suggestions?

I can attach the Review link if anyone thinks it could help. 

Thanks, 

Nate
