Automatic toggle custom play/pause at end of slide?

I´ve created a custom play/pause button as Lilybiri describes in her blog. The problem now is: I have several stops in my project, giving the learner time and opportunity to read and/or click. These stops are always at the end of a slide. At these moments the toggle buttom should change from its pause state to a play state. But the variable cpCmdPause in my script doesn`t notice that the projects pauses (because its an action depending on a click on the toggle button).

How can I get the toggle button and/or the action script to notice that the project stops at a specific time?
