Branching with option to hide layers
Before I start, I have had a look through the forum but I could not find what I was looking for....so here goes.
What I want to do is create a course for three different workers, each with different requirements.
The structure of the course contains a central "spine" of screens. These are called "overview" slides and give the learners an overview of an industrial process.
At they work there way through the course, an icon will appear IF there is extra information for them to see relavant to their role.
I have produced this manually where by I have three icons on each "spine" screen and it branches to a subset screen when clicked. Each icon represent a different job role.
This works great, but I want to take it a step further by offering the learner a choice at the start of the course to choose a job title and then only have relavant info to them appear.
So, if the first overview screen only has additional information for job role 1, only an icon for that job role appears.
If overview screen 2 has additional info for roles 2 and 3, then only those buttons appear.
I was wondering if I should do this by having the 3 buttons on 3 different layers, and switching off the layers I do not need...but I do not know how to do this from the original "choice" slide. Can you use a variable to switch off layers on every slide simultaneously?
Any help much appreciated
