Results slide and making the user review

Hello heroes,

I am wondering if anyone could tell me a way to make the user review the quiz before proceeding on to the next slide? I have tried hiding the next button on the failure slide and then showing the next button once the review quiz button changes states to selected. I have tried adding a variable t/f that once the review quiz button has been selected changes to true and then when variable is true change state of next button to normal. Nothing I do works. I can hide the next button but I can not get it to return so they can proceed. Any help would be appreciated!
