On 'Go to next slide' screen flashes white and resets slide instead.

Question

On the fifth slide of my project I have seven buttons to press before the 'next button appears. The first timne I hit the next button; the screen flashes white and the slide refreshes. If I try clicking the buttons a second time; I get to the fifth or sixth button and the screen flashes white and the slide resets again.

I've tried previewing the project from after this slide, in which case it gets even stranger: It will let me view no more than two slides before the next button simply doesn't do anything.

The only clue I have is may variable for number of total slides which should be a static variable (cpInfoSlideCount - 3) set on the first slide. It should equal 17, however when I preview from slide 6 it seems to be reading the current slide number instead (it increases by 1 on the next two slides).

Has anyone seen anything like this before? I'm completely lost.

First, if you don't have anything setup to debug your code, you're basically blind as to what is causing the problem. You should set up text boxes that will display the values of your variables somewhere on the slide.

I can't tell exactly what you're doing, in terms of what the learner has to accomplish to successfully complete a task, but, maybe something like this will work:

Declare a counter variable that will be incremented by 1 every time a user successfully completes a task (i.e. var_S5_TasksCompleted = 0).
Then declare a var to establish the total number of tasks the user needs to successfully complete (i.e. var_S5_TotalTasks = n)

Advanced action:

Every time a button is clicked/task is successfully completed, increment var_S5_TasksCompleted by 1 (make sure you disable the [button] or whatever interaction performed after a successful attempt so you prevent the counter var from being incremented more than once per task)
then have a conditional check if var_S5_TasksCompleted == var_S5_TotalTasks.
If true, show the Next button.
