Hi, lenyoga, thanks you for your help...
Well, I've opened the "scripts.sqs" file with the pboX tool, I've seen its content, and I able to see a file called "Onplayerkilled.sqs". I've made a .sqs file called "onplayerkilled.sqs" in my mission folder,at the beginning this script does not worked me, because missing this command ----> "enableEndDialog" Now this script worked well.
(Still have to improve my Spanish)
And I have to improve my English.
Saludos,
