Variable "AttemptCount"

Hello. Did anyone ever figure this out? I am having the same issue.  I recorded a screen simulation and imported the slides as Test mode so that it will be a quiz.   We are designing it where a user gets 3 attempts and after the second attempt, a highlight box appears to give them a hint as to where to click.  Now three slides did not have the AttemptCount variable as an option and I have no idea why.  I do not have a problem with the other slides.  I even re-recorded the steps for these three slides and it still is not working or giving me the AttemptCount variable.   I need to get this to work as part of a huge project I am responsible for and have many of these simulated system quizes I need to create.  Your help would be greatly appreciated!
