How to get the width/height of a layer in a script

[PerrowPhoto]

Hello all, I am trying to make a small script that resizes a layer (shrinking) to fit the canvas/image size... I am trying to do this by querying both the document width/height then comparing it to the layer width/height, but I cannot find any way to find the layer width/height... any suggestions? I have tried the code below but it brings back an 'undefined'.

app.preferences.rulerUnits = Units.PIXELS;
var docHeight = app.activeDocument.height;
//alert(docHeight);

var docWidth = app.activeDocument.width;
//alert(docWidth);

var layerWidth = app.activeDocument.activeLayer.width;
alert(layerWidth);
//this line above returns the 'undefined"

 How can I get the activeLayer width and height?

Thanks!

It's layer.bounds. I'm not into PS scripting, but I know at least that much. Hope it helps.

var theBounds = app.activeDocument.activeLayer.bounds;
var layerWidth = theBounds[2] - theBounds[0];
var layerHeight = theBounds[3] - theBounds[1];
