on (release) {} : tells Flash which action is going to trigger the commands that follow inside the brackets ( {} ) ; in this case, the release of a mouse click on the button.
gotoAndPlay () : tells Flash what action to perform after the trigger of a released click--it's going to go to something and play it.
"Blue Option" : tells Flash where it's going to perform the "play" part of the gotoAndPlay command. It's almost like a map that says "turn left at this street". Don’t' forget that it's separated by a comma from other parameters so that Flash knows to read them as separate things.
1 : tells Flash what frame number to start on when it gets to "Blue Option". If "Blue Option" says "turn left at this street", then "1" is the street address of the place on that street where you're going.
And you've just created a clickable button that actually plays something when you perform an action. You'll need to repeat his for your other options to complete the project. You can see my end result here.
