How to disable custom Next button until all hotspots clicked
So, I have an image that serves as my custom Next button. I want to disable this button until the learner has clicked on all of my hotspots. I have it set to the initial state: Disable, and am trying to figure out the right trigger to set it to 'Normal'.
I found this video for working with the default next button and set up my conditions for the initial hotspot to be "false" as outlined here with triggers for each variable to be "true" once the hotspot is clicked . However, the problem arises when I create the trigger for my custom button to change states.
Right now I have a trigger created to change the button state When: Variable changes. I apply it to one variable, then add conditions for all the other variables. However, it's not working to change the state to enabled once all those hotspots are selected. If I limit the trigger to only one hotspot variable and don't add additional conditions, then it does work to enable my button....but I need it to be configured so that they are required to click on all of them, not just one, in order to enable the button.
Here is a link to download project file (too big to attach here).
Help to get this working is appreciated
