Drag and drop - 1084Syntas error: expecting identifier before rightparen

Hi guys!

I am so unbelievable new to flash in general. I need help desperately! I have spent way too long searching google to try and find an answer to this. But I am trying to use drag and drop but my code keeps coming up wtih this error "Scene 1, Layer 'Actions', Frame 1, Line 20, Column 2 1084: Syntax error: expecting identifier before rightparen."

here is the code I am using

Doctor_mc.addEventListener(MouseEvent.MOUSE_DOWN, drag);

Doctor_mc.addEventListener(MouseEvent.MOUSE_UP, dropMusic_mc)

function drag (event:MouseEvent)

{

     event.currentTarget.startDrag();

}

function dropDoctor_mc(event:MouseEvent)

{

     stopDrag();

     if(Doctor_mc.hitTestObject(Doctortarget_mc))

     (

          Doctor_mc.x = Doctortarget_mc.x());

          Doctor_mc.y = Doctortarget_mc.y();

     )

}

PLEASE HELP!
