Strange way to create a quiz that way, but will try to answer your question. It may be overwhelming for a new Captivate user, would recommend to start with creating a simple quiz, not one with a Forced view dashboard slide.
You will need:
- 9 tracking variables, one for each of the buttons; will label them v_1, v_2..... v_9. Their start value = 0. Add another one called 'v_counter' also start value 0
- For the buttons you'll have to replace the Jump to slide, by an advanced - or better a shared - action. There are multiple ways but it will be something like this:
First decision tab 'Always' non conditional
Jump to slide.... indicate the question slide
Increment v_x the variable associated with this button
Second decision tab 'Counter' conditional
IF v_1 is equal to 1
Increment v_counter
If you create this as a shared action, you will have two parameters:
v_1 needs to become a parameter since it needs to be changed on each assignment of the action
slide.... the question slide
If you don't want a shared action, you would need to duplicate the advanced action to end up with 9 different advanced actions.
Assign those actions to the Success event of the buttons.
For the appearance of the Continue button, you'll need another advanced action, to be triggered by the On Enter event of that dashboard slide. That one will have only one conditional decision:
IF v_counter is equal to 9
Show Continue button
ELSE
Hide Continue button
I really wonder why you want to have such a setup for quiz slides?
BTW I will coach a workshop about advanced and shared actions on 23rd of September, in the Adobe eLearning World conference. Registration is free...
