Storyline- Next button to become available after visiting another slide

Thanm you so much Mike! I think I am going to try this as it seems to work a bit better than what I have done.

I actually ended up going around it in a different way but similar process. On the main page, I have created a variable. The variable is set to 0. When you click the back button on the linked page, It adds 1 to the variable each time. Once the variable reaches 6, there is a trigger that says, change the state of the next button to available when the variable is equal to or greater than 6.

Thanks so much for your example! :)
