Restricting audio completion
I have a slide that has 3 images and when the learner clicks on each image it changes state to visited, shows text and plays audio. The problem is that the learner doesn't have to finish the initial narration before they can click on an image. So, there are two narrations playing and potentially four - initial, image 1, image 2 and image 3. I've been viewing and reading tutorials and don't understand how the variables, conditions and triggers work together and how I can use some or all of them to have the learner complete each audio before being able to click on the next.
Has anyone experienced this and can you help me? I've done very little work with variables and conditions in SL.
