PS运行js脚本提示：liveobject()不是函数

功能大致如下：根据图片名称、字数创建若干文字层，并调整字号与位置，以下是字数小于15的情况的代码。文字居中部分使用的是监听出来的脚本。

var docRef=activeDocument

app.preferences.rulerUnits = Units.PIXELS
app.preferences.typeUnits = TypeUnits.PIXELS

var h = app.activeDocument.height
var w = app.activeDocument.width

var docname =activeDocument.name
var Dot = docname.lastIndexOf('.')
var rdocname = docname.substring(0,Dot)

//alert(rdocname.length)

if (rdocname.length<16) {

var layerRef=docRef.artLayers.add()
layerRef.kind=LayerKind.TEXT
var textItemRef=layerRef.textItem

var textcolor= new SolidColor
textcolor.rgb.red=255
textcolor.rgb.green=255
textcolor.rgb.blue=255
textItemRef.color=textcolor

textItemRef.font= "楷体"

textItemRef.contents = rdocname

textItemRef.size=29-rdocname.length
textItemRef.justification=Justification.CENTER

还望大神不吝赐教，另外如果我想在function SELECT……这些函数里面传递rdocname参数可以吗，比如把“从不四渡赤水”改成rdocname？要如何编写呢？本人JS小白……
