heres a way that will (should ???) work: create 4 command sequences (play1, play2, nextchapter, progstart), and set the end action of all the chapters to 1 command sequence (nextchapter), this command sequence will basically look up GPRM1 and goto one of the other command sequences (play1 and play2) the play1 and play2 command sequences will do this: add 1 to GPRM2 (counter), then select the next chapter based on this new value, ie, if the counter becomes 3, then in the first playlist in your earlier post it would play Movies1 Chapter2. the last command sequence is what you'll link your button(s) to, not sure if you need two of this one (or one for each button), but this will basically set GPRM1 to 1 or 2 (for which play you want) and set the counter to 0. now if that confused you even more, then i might get a chance to translate that to command sequence code, altho it is close (in my logical mind) but i know i might have left out something, but give it a try anyway.
