Button from Base Layer SHowing up On Other Layers EVen though Hidden?

Walt,

Thank you for the great info! It's nice to see the explanations put that way in one place. I have found I have difficulty applying info presented in basic tutorials (on both the articulate site and YouTube videos I find on my own of various "superusers" of Storyline 360) into my own projects.

I so want to be able to use the built-in states! And to learn to use them properly! I don't expect to ever be developing elaborate, complex slides for my purposes, so the type of interaction I submitted yesterday will likely be the extent of it. 

I have tried to use all of your advice about using the built-ins and removing any triggers I created associated with them. (Please see the attached set of 3 slides - the one before and the one after are simply there for testing out the next button). 

Here's my dilemma:

• I need to have the slide locked down and the learner must complete all items on the slide before being allowed to move ahead. Therefore, I have chosen to restrict the menu and restrict the navigation. This is a 2-hour course with lots of slides but very few of them have layers.
• I do not want them to have to re-click on the buttons again upon re-visit (unless they want to...if that is even possible). I thought I had it figured out except...if they don't hit the "Back Button" to close out the last layer for the last button they select, the next button is opened up (I assume by rule of "Clicking = visited") and they can move ahead. I’m not overly concerned if they simply blow off reading the content on the last clicked button before moving on, as I suppose that’s the worst thing that could happen. But also, if they decide to go back to the slide and start clicking around on that last layer (that never went back to the base layer), the clicking around on that revisted slide eventually causes the next button to no longer be enabled and the learner is stuck (I've set the slide properties to Resume Saved State upon re-visit).
• Is there anything I can do to prevent this?
• Or, have I set things up incorrectly? 

Thank you again for helping me learn this tool!
