I'm looking for a way to trigger a state change from disabled to normal, using a variables value? I want the user to visit 10 slides before a button becomes available to branch to a new section.
My Variable is counting correctly, but it never changes the state of the disabled or hidden button(or shape) to normal.
It's hard to troubleshoot something like this without seeing the .story file, but I'll give it a try.
Here's a typical cause for that sort of problem: The trigger to change the state is set to run when the variable changes. But the variable changes on another slide. That means the trigger will never "see" the variable change, so it'll never run.
If that's the case, what you need instead is a trigger that runs when something happens on the slide (e.g., the timeline starts), and with a condition that checks the variable's value.
This post might be helpful. It's about controlling the Next button. However, the same basic steps apply for enabling another button.
What is your trigger event for this change? It should NOT be when the variable changes? I would recommend "when the timeline starts", under the condition that your variables have changed.
I was asking the scene to check the value when the 'Variable changes' as a part of an Object trigger, when I needed to check the value on a Slide Trigger during a 'Timeline Start'...
and voilà just like that it works.
I scratched my head and read several blogs on this one, for quite a few hours, Thank you!

If this is indeed your issue, we wrote a BLOG about this - https://www.thearticulatetrainer.com/how-do-i-use-when-variable-changes/
Judy's post came through while I was typing mine . . . so . . . what she said :)
Judy and Ron,
You guessed it exactly!
