Disable/enable Next button

Easiest would be to use custom variables. When each of your buttons are clicked set the variable to a value that you know is the value that confirms they clicked all the things you want. Then you can use an action to listen for the variables value to match and enable the Next button when they do. 

See the attached Capture that shows how to use a variable condition to enable the Next button. 

This is very helpful. Thanks a lot.

I have followed the instructions in the video above, but something is not working. Either the Next button becomes enabled after only one of the items is clicked, or it doesn't become enabled at all after both items are clicked. Clearly, I am missing something here. Maybe I have not created the variable correctly? Is there an instruction on how to create this variable, AllClicked(number)?

Thanks.

Luke, The requirement from our client is that all content be viewed before the learner can move to the next page. As this is a certification course, they are required to see all the content. Some pages have multiple hyperlinks. The bigger challenge is that there are hyperlinks embedded in carousels and accordians, and all of them need to be viewed before the Next button can be enabled. It's getting complicated. Any guidance you can provide in creating the necessary variables to execute this functionality would be greatly appreciated. Thanks.
