Actionscript for a mouseclick

hi everyone,
I have a question , how to write a actionscript code for a button when the button is clicked it should move to the nextframe.
// About and smile1 button scripts
_root.smile1.onPress = function() {
if (mouse_over_smile1) {
} else {

// animation for the smile2 button

_root.smile2.onRelease = function() {
if (mouse_press_smile2) {
} else {
// animation for the smile3 button

_root.smile3.onEnterFrame = function() {
if (mouse_over_smile3) {
} else {

i have given 3 functions as onEnterFrame,onPress,onRelease. i tried all these but didnt get the result.
smile1,smile2,smile3 are button instances which are declared on the monie clip.
my main thing is i hav a button, when i click on that button it should go the next frame which i have declared in “gotoAndPlay(6)” method. can any one write the code for me.
i need it urgently.
Thank You.
