Some urgent help needed - slowing down a vertical movement of blur text

programming flash
1

Hi,

I have a Movieclip on scene 1 named testMC.

I have a button on scene 1 named myButton.

Actionscript in myButton:

 
 
on (rollOver) {
 
 tellTarget ("/rollover") {
  gotoAndPlay("namn1start");
  
 }
}

Actionscript in **testMC **symbol:

onClipEvent (enterFrame) {
 //generating movement
 location = this._x;
 var i;
//speed
 i=40;
 //i = 1+_root._xmouse/5;
 if (this, hitTest(_root.block)) {
  this._x = -1000;
 } else {
  
  this._x = location+i++;
 }
 
}

This create a movement to the test MC symbol.

But how do I slow down the movement in testMC when I roll over with the mouse on the button? I don’t want the movement to be depending on x and y of the mouse, so that it speed up when dragging mouse right and slowing down when dragging mouse to the left.

I want a nice equal speed (slower than it’s original speed) of the testMC when I mouse over the button.
