Replace entire content not working

I have T(-) Countdown Control running a set of timers that should then switch to an audio delivery. I would like to have the countdown timer disappear and be replaced with the audio player. I *think* this is what the “Entire Content” option should do, but it doesn’t work at all — just leaves timer with all zeros and no content served. Above and below work sort of ok, the audio player loads on a refresh but doesn’t come end otherwise. Any ideas?

The page is at http://businessbuilderstoolkit.tightship.us/listen-to-the-telesummit/ The second entry is a timer that I’ve set to time out already.
