Button for audio

Question

I'm using a tutorial from flashkit.com to make a simple
button for audio on/off. Here's is the tutorial
Step One:
Create two buttons in your graphics program, one for
switching the music off and one for switching the music on.
Step Two:
Put both buttons into one Movie Clip. Each button on a
seperate frame. So you will have a MC with the first frame with the
"MUSIC OFF" button and the 2nd frame of the MC will contain the
"MUSIC ON" button.
Step Three:
Open the actions for the first frame of the MC and put in
this code:
stop();
and for the other frame add (The frame with MUSIC ON):
stop();
stopAllSounds();
Step Four:
Go to the first frame and open the actions for the button
(MUSIC OFF button):
on (release) {
gotoAndPlay(2);
Then for the MUSIC ON button add the same code but replace
the 2 with a one.
Step Five:
Now import your music file into Flash (Go to FILE>>
IMPORT) then go to your first frame of the MC and add your sound
into it. Under LOOP NUMBER put a big number like 9999 so the music
will go on for a long time.
I made my "button" in photoshop, and import it into flash,
its showing as a bitmap (I've tried saving it as a jpg, gif, and
png) when I preview my button after importing the music and adding
the script to each layer it plays the music, but you cant click on
it to turn the music on/off. I get this Error in preview
**Error** Scene=Scene 1, layer=on, frame=1:Line 3: Mouse
events are permitted only for button instances
on (release) {
**Error** Scene=Scene 1, layer=off, frame=1:Line 2: Mouse
events are permitted only for button instances
on (release) {
Total ActionScript Errors: 2 Reported Errors: 2
**Error** Scene=Scene 1, layer=on, frame=1:Line 3: Mouse

on (release) {
**Error** Scene=Scene 1, layer=off, frame=1:Line 2: Mouse
events are permitted only for button instances
on (release) {
Total ActionScript Errors: 2 Reported Errors: 2
What am I doing wrong? And how do I make my image into a
button? Thank for any help!

the button has to be actual flash BUTTON instance not just
button image.
You need to convert each symbol into BUTTON.
