Class in Action script 3

Hi All
I am new to action script 2.o
please help me in the following coding
in .fla the code is


var trail:threedots = new threedots();

trail.drawtri();
onMouseMove = function(){
    trail.MouseMove();
}

onEnterFrame = function(){
    trail.EnterFrame();
}
onMouseDown=function()
{
    trail.MouseDown();
}

btnReset.onPress=function()
{
    trail.btnReset1();
}

in .as file

function btnReset1()

    clicks=0;
    triangle._visible=false;
    c1._visible=false;
    c2._visible=false;
    c3._visible=false;
}
}

when i compied i got the following error
