Hi please help me... this is about button movie clips

Hi, please help me i have a portfolio site.
this is all going well until i go to the portfolio page in a new scene,
i make an array button with a movieclip name fm_button. the problem is after i go to the portfolio scene and if i want to go to the other scene, ex(aboutme or index) the fm_button is still there…TT

I already tried, remove movieclip, visible false (like what i did in red color in this as) but it didnt work…
please help me out… thanks

fm_button._visible = false;

button_label[5] = “5”;
button_label[6] = “6”;
button_label[7] = “7”;
button_label[8] = “8”;

// a number of buttons in button_label array must be equal
// to a number of frames inside “contents” movieclip

j = Math.round(no % 3);
k = Math.floor(no / 3);

new_position_x = original_x - j * distance_x;
old_position_x = contents_group._x;
new_position_y = original_y - k * distance_y;
old_position_y = contents_group._y;

new Tween(contents_group, "_x", Elastic.easeOut, old_position_x, new_position_x, 2, true);
new Tween(contents_group, "_y", Elastic.easeOut, old_position_y, new_position_y, 2, true);

}
changeContent(0);

// this is an if statement to make fm_button dissapear when i go to other scene, but it didnt work, should i make [COLOR=Red]fm_button._visible = false[/COLOR] in the portfolio scene or other scene? any help?
[COLOR=Red]if(intro_btn.onRelease = function (){
gotoAndPlay(“intro”, 0)
}){fm_button._visible = false;
}[/COLOR]

aboutme_btn.onRelease = function (){
gotoAndPlay(“aboutme”, 1);
};

portfolio_btn.onRelease = function (){
gotoAndPlay(“portfolio”, 2);
};

index_btn.onRelease = function (){
gotoAndPlay(“index”, 3);
};

contactme_btn.onRelease = function (){
gotoAndPlay(“contactme”, 4);
};

Thanks so much for all ur help^^
