Can anyone help me out w/ a simple question?

Question

I need a little help getting this to work. This is my first script so go easy on me! 8)
I looked at the forums but being that this is my first script it's still too difficult to decipher everything. In my document that's already open I want the script to make a text box of 50 pixels (for example) and insert my text inside it. Here's what I have...
// Create new text layer
var artLayerRef = activeDocument.artLayers.add()
artLayerRef.kind = LayerKind.TEXT
// Make text BOX on text layer
TextType.PARAGRAPHTEXT.width = 50
// Add text to text layer
var textItemRef = artLayerRef.textItem 
textItemRef.contents = "My Text Here. My Text Here. My Text Here" 
// End 
artLayerRef = null 
textItemRef = null 
It places the text but doesn't put it in a text box. It's just a line of text that extends off of the page. Anybody know what I can do?
Thanks you!

Hi Mike, even setting unit values don't seem to work so have to resort back to the 72ppi
var res=activeDocument.resolution;
var artLayerRef = activeDocument.artLayers.add()
artLayerRef.kind = LayerKind.TEXT
var textItemRef = artLayerRef.textItem
// Make text BOX on text layer
textItemRef.kind = TextType.PARAGRAPHTEXT;
textItemRef.width = 50/(res/72); //width in pixels
textItemRef.height = 100/(res/72);//height in pixels
// Add text to text layer
textItemRef.contents = "My Text Here. My Text Here. My Text Here."
