Ok so i installed flash a few days ago, and my friend gave me an actionscript to use to make flashes but its not working. Is my script not detailed enough? Do i need better stage directions? Can anyone help me?

setMovietitle (Tanks on Rampage);

TotalFrames (540);

setscript "Green Tank rolling over a school bus, a bus driver named Otto jumps out of it and begins climbing the tank, he jumps inside and knocks the guy out and begins driving the tank into the sunset";

startAnimation;

gotoAndPlay(1);
