how to disable a variable interaction after one use
Nov 10, 2021
Hi, I'm really hoping some can help me please!
I have a created a course which contains 6 sections. Each section has a summary slide. On each summary slide I have created a variable to change in value once the slide is visited. On the main menu slide where you access all 6 sections I have set it to jump to the final assessment once the user has completed all 6 sections (so they need to have visited the summary slide of all 6) and all 6 variables have had their value change. This all works perfectly... however if a user navigates to one of the summary slides twice and then to the main menu it means the 6 sections can appear completed but the course doesn't jump to the final assessment and gets stuck.
So my question is how can I fix this? Is there a way of either:
- Preventing a user from accessing any of the summary slides twice?
- Disabling the variable from changing in value after the first time?
- Adding a layer on the summary slide which is shown if the user visits it again and therefore stops the variable changing again?
- Something other than the above?
Any help would be hugely appreciated, thank you
