Rotating movieclip and changing to a particular frame (S.O.S)

I would apreciate if someone help me with some coding.

I have this code that I previously get to rotate a movieclip with the mouse, and get to another frame, for a college work (we only did the tweens, just learned the basic coding) but I cant get no result.

import flash.events.Event;
import flash.events.MouseEvent;

leme_mc.addEventListener(MouseEvent.MOUSE_DOWN, rotate);
stage.addEventListener(MouseEvent.MOUSE_UP, endrotate );
var angulo:Number=0

function rotate(e:Event😞void
{
  stage.addEventListener(MouseEvent.MOUSE_MOVE,rotate);


   var position:Number = Math.atan2(mouseY - knob_mc.y,mouseX - knob_mc.x);


  angle=(position/Math.PI) *180;
  knob_mc.rotation = angle;

}

function endrotate(e:MouseEvent😞void
{
  knob_mc.removeEventListener(MouseEvent.MOUSE_DOWN, rotate);
  stage.removeEventListener(MouseEvent.MOUSE_UP, menu);
  stage.removeEventListener(MouseEvent.MOUSE_MOVE,rotate);
  knob_mc.addEventListener(MouseEvent.MOUSE_DOWN,rotate);
}

function menu(e:MouseEvent😞void
{
   if ( angle >=1 && angle <= 100 )
   {
  gotoAndPlay(2);
   }
   else if (angle >=100 && angle < 340) {
  gotoAndPlay(2);
  

I made the movieclip move with the mouse, the knob_mc rotate when i press and move the mouse but i can't get the AS3 script to make the angle in the If's jump to another frame.
