Problem changing the state of a button on a different slide

I'm using a trigger and a True/False variable on slide x to change the state of a button on slide y.  On slide y, I have set the condition that if the variable has changed (which I've confirmed it has), then the state of the button changes from Disabled to Normal when the TIMELINE BEGINS.  Unfortunately, when I publish and view the course, the button on slide y still appears Disabled and only changes to Normal IF I roll over it.  There are no triggers for any Hover conditions so I don't know why the state of the button won't just change automatically when the timeline starts. Any help would be greatly appreciated.
