Only First function executes

OK first i tried this.........
this.home_mc.onRelease = function() {
if (menu_mc._currentframe == 51){
menu_mc.gotoAndPlay("_secondmenu");
}
}

this.home_mc.onRelease = function() {
if (menu_mc._currentframe == 82){
menu_mc.gotoAndPlay("_sixthmenu");
}
}


Then I tried this.......

this.home_mc.onRelease = function() {
if (menu_mc._currentframe == 82){
menu_mc.gotoAndPlay("_sixthmenu");
if (menu_mc._currentframe == 51){
menu_mc.gotoAndPlay("_secondmenu");
}
}
}

Whats happening is only the first function executes, does anybody know why?
What is it ?

    if (menu_mc._currentframe == 82) {
        menu_mc.gotoAndPlay("_sixthmenu");
    } else if (menu_mc._currentframe == 51) {
        menu_mc.gotoAndPlay("_secondmenu");
