Display a certificate after passing second attempt

Hello everyone, I have a quiz that I want students to pass with 70% . They have 2 attempts.  When they achieve the 70 or more, I want them to access the certificate of completion. Problem is, I don't know how to setup the variables to display the certificate when they pass the quiz after the 2nd attempt.

If they pass the quiz after the first attempt, they can print the certificate. it works fine. However, if they fail the first attempt and they pass it the second time, they can't print the certificate. I think articulate is remembering the score from the first attempt. I need something to tell Articulate to provide a certificate when the user passes the second attempt.  HOw would I set this up?

Thanks
