Storing current slide in a variable, then using the variable to get back to that slide (Captivate 6)

Question

I'm thinking there must be some info on this somewhere, because it's something people must want to do, but I haven't been able to find an answer.
I would like to set something up so that when a user clicks on a button, it will take them to a certain slide. But I want the current slide stored in a variable. And then, when they are ready to go back, there will be a return button, but it should check to see where they came from and then return them to that specific slide. Basically, a "return to last slide visited" type of advanced action. I can't use the "return to last slide" option because the slide they are taken to when they first click the button has multiple slides, so the "return to last slide" option would not take them to the last slide they were on before visiting this page. I tried to store this in a variable on a button click by assigning a variable with CpInfoCurrentSlide, and then jumping to a slide. But, I'm not sure how I would then use that info to return to this slide.

Captivate Advanced Actions don't actually provide an easy way to do this.  It's another area we really need to address in forthcoming versions.
You need to use an On Enter Slide event to store the value of the cpInfoCurrentSlide system variable in a user variable.
Then you need to create another advanced action that can be triggered by your later button.  Somewhat counterintuitively, you need to use an Expression action (rather than an Assign action) to assign the value captured in your user variable to cpCmndGotoSlide.  But that's not all.  Due to the way Captivate's slide indexes work, you'll need to deduct one from the value of your user variable before assigning it to cpCmndGotoSlide.
Then, unless you want the slide timeline to pause, you need to add a Continue action.
The final action looks a bit like this:
