prema volta et secondo volta (first & second endings)

Thanks underquark. I used both techniques and they both produce a score that looks great but I can't get the playback to work correctly. The first time through the first ending is played. But when it reaches the end repeat sign in measure 60 it simply stops if I have play repeats enabled. I was expecting it to return to and play a second time from the begin repeat sign at measure 5. If play repeats is disabled it plays the first ending followed immediaely by the second ending.

What did I do wrong this time?
