Flash 8 - Simple (for Sum) Button Programming

So I am trying to get better at putting all my code within one action layer and there is a bit of button code that seems to be confusing me.

Whenever I program a button I use the following code:
PHP Code:
on (press){
} on (release, releaseOutside ) {
}

Now I know programming the on(press) command is done like this:
PHP Code:
btnName.onPress = function() {
}

However I am having a hard time with the on (release, releaseOutside ) code. The only way I have been able to do it is like this:
PHP Code:
btnName.onRelease = function() {
} btnName.onReleaseOutside= function() {
}

My question is, is there any way to combine the two onRelease commands?
