Linkage Problem (I think)

I don’t know. this same tutorial (I admit it) worked in flash 5. But the Linkage window is different in MX 2004. I gave it the right Identifyer so thats not the problem. Can you help?

Just in case it’s not the linkage that’s the problem:

mySound - new Sound();
mySound.attachSound("Tune");
mySound.start("",999);

Is that code dated as well?
