Could someone help (removeMovieClip) w/as2.0 or 3.0?

I’m using ActionScript2.0 and 3.0…Trying to remove an object off stage when the user select two of a pair. Here a simple of what I’m doing.:stare:

on (release)
{
if (_name eq “btn1”)
{
setProperty("/btn1", _visible, “0”);
++_root.step;
++_root.checking;
if (_root.checking == 1)
{
_root.option1 = _root.img2[0];
_root.firstbtn = “btn1”;
}
else if (_root.checking >= 2)
{
_root.option2 = _root.img2[0];
_root.checking = 0;
_root.secondbtn = “btn1”;
_root.gotoAndPlay(4);
} // end if
} // end else if
