Problems with variables

Hi there,

Hope that someone can help me out with some variables I'm using as I can't see what the issue is with them.

I have a screen that serves as a menu, with three topic buttons on it that then branch to the relevant topic content.  I've tried to set up variables to create a traffic-light system on the menu, whereby:

Red = the topic has not yet been accessed at all

Amber = the learning for the topic has been completed but the quiz hasn't been taken/passed

Green = both the learning and the quiz have been successfully completed

I've set up a true/false variable for the amber status and a trigger on the final learning page to adjust it when the learner clicks on a button to go back to the menu:

Set "Learning" equal to True when user clicks

and another for the test element that says:

Set "Test" equal to True when user clicks (this is on a button that takes the user back to the menu)

if Results.ScorePercent is greater than or equal to 80

I've then got a trigger on the traffic light graphics back on the menu page that should alter the state of the graphic with these conditions:

Change state of traffic light to

Learning Complete

When Learning changes

If Learning = True

and Test = False

or Results.ScorePercent > 80

Change state of traffic light to

Quiz passed

When Test changes

If Test = True

and Results.ScorePercent => 80

I've tested this out a few time in preview mode and nothing changes with the states at all.  Can anyone please identify what I'm doing wrong here?

Thanks,

Laura
