How can I put move requests in stuck and continue working?

Question

I have a map and a unit moving on this map, I wont to give him 2 moving orders and continue for my another staff.
this is part of my program so I try to explain to you the parameters of this function in the way I choose to represent it:
destination:String is a string looking like this: "x,y" where x and y are the coronations.
getLocNum(location:String, isX:boolean) returns the x value if isX set to true or the y value if its false.
_units is an Array with images and you can ignore from unitID for now.
_location:String is also a string form "x,y" family, that show the correct unit location.
I hope this were clear enough for you to try and help me out with this.
Here we go:
public function testMoveUnit(destination:String,unitID:int=0):void
var myMove:Move=new Move();
myMove.target=_units[unitID];
myMove.xTo=getLocNum(destination,true)*30+38;
myMove.duration=Math.abs(getLocNum(destination,true)-getLocNum(_location,true))*1000;
myMove.play();
myMove.yTo=getLocNum(destination,false)*30-28;
myMove.duration=Math.abs(getLocNum(destination,false)-getLocNum(_location,false))*1000;
myMove.play();
_location=destination;
Right now the unit only moves for his x direction and if I remove the first myMove.play() request so its going for the destination, so the only problem is when I am adding my first move().
And for another question may be more complicated then that is how can I know if my unit is in a middle of his move and I don't wont to interrupt him right now, I mean at the future when the function be called again.

sorry for missunderstanding about Move
possibly its not working because you are calling myMove.play() twice and setting duration twice , try omitting one myMove.play() like below
public function testMoveUnit(destination:String,unitID:int=0):void
var myMove:Move=new Move();
myMove.target=_units[unitID];
myMove.xTo=getLocNum(destination,true)*30+38;
myMove.duration=Math.abs(getLocNum(destination,true)-getLocNum(_location,true))* 1000;
myMove.yTo=getLocNum(destination,false)*30-28;
myMove.play()
_location=destination;
