Well, I am very missed I was tried to use "if" to bypass the transition function without success, inspired in this message:
http://sourceforge.net/mailarchive/message.php?msg_id=20187957 if source.id(s) == "tangos" then transition function... end Of course I was added the ID to the playlist like: playlist(id="tangos",...) Any help will be appreciated (yes, more help :-) Normando El 20/12/2010 01:56 p.m., Normando Hall escribió: > Thank you David.
