Variable toggle not functioning as explected

Thank you  - but one more question.  Say there are 10 slides, all of them have a version attached to the variable being true and also a version for the variable being false.   If the learner clicks 'a' on the first slide (making the variable true) will all of the subsequent slides show the 'True' version?  At the moment, that doesn't seem to be the case for me.  It is more likely that the learner will make that selection only once.  While it would be nice for them to be able to toggle on each slide, it is unlikely that they would do so.
