i take an error about package what is wrong in this code?thanks

You need to create a new file called SetTimeoutExample.as, and put the code in there. Make sure that the file is in the same directory as player.fla. Then open player.fla, and in the properties window (Window > Properties), set the "Class" field to SetTimeoutExample (without the .as).
