[CS3] Actionscript help with scaling please

[JoshG021]

Hello, I need help floating an object in flash. I am using actionscript 2.0 because some of the other coding stuff I'm doing will only work in that.
I am scaling an object called sight 1, in relationship to it's distance from the sight object. With some help I got this code to work for what I am doing, but I can't figure out how to make it scale smaller the further away it is, rather than larger, like it is now. Some of the code is moving the sight1 object around randomly. Thank you.

//Sight 1
sight1.goalX = Math.random()*(650 -sight1._width)
sight1.goalY = Math.random()*(515 -sight1._height)
sight1.xSpeed = 20
sight1.ySpeed = 20
sight1.onEnterFrame=function() {
this.xDifference = this.goalX - this._x
this._x += this.xDifference/this.xSpeed
this.yDifference = this.goalY - this._y
this._y += this.yDifference/this.ySpeed
this.xDelta = this._x - sight._x
this.yDelta = this._y - sight._y
this.myDistance = Math.sqrt(Math.pow(this.xDelta,2)-Math.pow(this.yDelta,2))
this._xscale += (this.myDistance - this._xscale)/this.ySpeed
this._yscale += (this.myDistance - this._yscale)/this.ySpeed
if (Math.abs(this.xDifference)<10){
this.goalX = Math.random()*(650 -sight1._width)
this.xSpeed = 5+Math.random()*20

}
if (Math.abs(this.yDifference)<10){
this.goalY = Math.random()*(515-sight1._height)
this.ySpeed = 5+Math.random()*20
}
}

Does anyone know of a possible solution for this? Thanks.
