Flash Button Activation

I am having a bit of difficulty with button activation. I have designed a new button and converted it to a symbol. I then wanted to have the button play a sound on its release. I tried multiple codes and many techniques but all proved to fail. What is the correct code for making a button play a sound on its release?

onRelease {

This is the code that I used to play a frame labeled “C”. I also tried this code where the
“C” was replaced with the actual frame, frame 94.
Thanks in advance.
