Convert actionscript 1 to actionscript 3

[dirtcreative]

Hi – can someone help with converting this Actionscript 1 to Actionscript 3

(Syntax error: expecting identifier before colon.)

loadMovie("leader.swf", "subHold");

lr1.gotoAndStop(1);

if (_root.links.:mlink==1) {

  play();

  _root.links.:mlink=0;

} else {

  stop();

}

And,

(Access of undefined property lr2)

lr2.gotoAndStop(1);
