grid doesn't listen to my slider

hey there

i did a code that zooms in and out a casket grid with the help of a slider. the grid works perfect with

a ready-made slider, but not with my own one and it has to work with the own slider...

what's wrong in my code? i think it's just a little thing that's not working, but i don't know what...

the slider is convoluted like this: "sliderG" and subordinated "thumb" and "bahn"...so the thumb

should move in the x direction of "bahn"-values...and i put the slider at a position of (0|0)...

can anyone help me?

thanks!

here's my code:

var pattern:BitmapData = createPatternOffset( [0xFF0000, 0x00FF00, 0x0000FF] );

//var drawPattern:int = map(sliderG.x, sliderG.x, sliderG.x+sliderG.width, 0, 100);

// this is where the code of my slider starts

sliderG.thumb.addEventListener(Event.CHANGE, f);

sliderG.thumb.liveDragging = true;

sliderG.thumb.buttonMode = true;

sliderG.thumb.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownGHandler);

sliderG.thumb.addEventListener(MouseEvent.MOUSE_UP, mouseUpGHandler);

sliderG.thumb.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveGHandler);

function mouseDownGHandler(event:MouseEvent):void {

sliderG.thumb.startDrag(false, sliderG.bahn);

}

function mouseUpGHandler(event:MouseEvent):void {

sliderG.thumb.stopDrag();

}

function mouseMoveGHandler(event:MouseEvent):void {

var sliderMax:Number = 400;

var sliderMin:Number = 0;      

function moveSlider(event:MouseEvent):void {

    sliderG.thumb.x = Math.max( sliderMin, Math.min( sliderMax, mouseX) );

dispatchEvent(new Event(Event.CHANGED, true, true));

}

}

f();

// here is the code of the pixel grid

function f(e:Event=null):void

{

    var sf:Number = 100 / sliderG.thumb.value;

    graphics.clear();

    drawPattern(graphics,100, 30, 300, 300, sf, sf, false);

}

function createPatternOffset(cols:Array, transparency:Boolean=false):BitmapData

{

    var len:int = cols.length;

    var bd:BitmapData = new BitmapData(len,len,transparency,0);

    for (var y:int = 0; y<len; ++y)

    {

        for (var x:int = 0; x<len; ++x)

        {

            bd.setPixel32(x, y, cols[(x-y+len)%len] | (transparency? 0: 0xFF000000));

        }

    }

    return bd;

}

function drawPattern(canvas:Graphics, x:Number, y:Number, width:Number, height:Number, scaleX:Number=1, scaleY:Number=1, smoothing:Boolean=false):void

{

    canvas.beginBitmapFill(pattern, new Matrix(scaleX, 0, 0, scaleY, x, y), true, smoothing);

    canvas.drawRect(x, y, width, height);

    canvas.endFill();

}

//pixel grid end
