OK, here is a live test survey

. In my normal survey method 1 does not work in live mode--only in preview, but here method 1 works. The bug ticket mentions methods 2 and 3, and they do not work in either this test survey or my real survey.
Meanwhile, the JavaScript does not fire in my real survey except in preview mode, so as a workaround to save time in debugging it, I made 8 questions and am showing one at a time using a relevance equation.
