Indeed it's possible. You will need to define a variable to track if the slides have been played. Then have your conditional statement check the value of the variable.

Hello again

As you enter or exit slides you are able to assign an action. So what you could do is to assign an action that updates a variable based on the slide(s) having been viewed.

I do not know if it should be a 'counter', should know some more details. You are talking about a 'sequence of slides', it is possible for the user to get out of that sequence and only visit first and last slide of that sequence? Do you provide a playbar? Because in that case the user can scrub the progress bar and visit the slide very quickly that way. It needs some more reflection. Be careful with counters if you allow backwards movement, which is possible with a playbar: using a counter that will be incremented on entering a slide will fail if the user instead of visiting slides 11-20 visits 5 times slides 11-12, because the counter will result in 10 in both situations.

Sorry for my remarks, but if you want help I need a clear image of the situation.

OK, picture is already more clear. But I still do not know, for the Floor groups or the Subject groups of slides: will the user be able to navigate back in those slides? Do you provide a default playbar (because then it is possible of course) or is everything controlled by own navigation?

I already understood this, like an example:

• if they choose to search by floor, they get a list with  floors (on another slide?-
• if they choose by subject, they get a list with subjects
• choosing a floor, they will visit (linearly?) slides 12-20 and return to general slide (with floor vs subject choice) or to slide with floors choice only?
• for a subject they will go to15-18 or will it also be possible to slides from different floor groups? After visit they return to general slide (with floor vs subject choice) or to slide with subjects choice only?

Anyway you'll need a user variable that stores the choice (perhaps 1 for floors, and 2 for subjects). But then I need more answers

You do not tell how exactly your 'IF' condition is written in the AA dialog box?

I would create a user variable, will label it v_source, no need to give it a default value. The statement:

Assign v_source with 1

should be added to every button/click box on the subject slide, that navigates to some slide about a subject.

A similar statement

Assign v_source with 2

should be added to every button/click box on the floor slide, that navigates to a floor sequence

On all possible end slides...you'll need the conditional action

IF v_source is equal to 2

THEN Navigate to ..... floor choice slide

            Continue

ELSE Navigate to ... subject choice slide

            Continue
