Both ways finally work! :)
I changed my capital letters and also the word "trigger" to "play", and it worked quite well, but your way, GoToLoop, works much better and faster! Well, I am really new in such experience, as you understand, but the more I try, the more I get excited... :) I will study more, also to understand exactly what you did, so that my next questions will be more advanced. :P
Thank you both very much!!!!!! :)
