Scripting Transform for user interaction

Question

I'm trying to create a vector layer in PS CS6 that is used as a cropping guide for portraits.  When I try to apply a transform to this layer, the transform box comes up but I can't change anything.  I've done a search for this, and seen some examples from Mike and Paul, but they all will not allow me to change the transform.

You may want to make sure what the Photoshop target is when you do the transform and also make sure there is no active selection.  Like perhaps set the which layer is the active active layer and target the RGB channel. Free Transform may have some options disabled depending on layer type.  For example if the current targeted layer is a text layer distort and perspective transforms can not be done. You would need to convert the text layer to a shape layer first to do that type of transform. You may want to also have a try catch to allow cancel for if no change is made ENTER as well as ESC cancels the transform.
activeDocument.selection.deselect();
try{
InteractiveTransform()
}catch(e){alert("Image Transform Canceled");}  //  or have no message
function InteractiveTransform() {
  // Menu Edit>Free transform
    var desc1 = new ActionDescriptor();
    var ref1 = new ActionReference();
    ref1.putEnumerated(cTID('Mn  '), cTID('MnIt'), cTID('FrTr'));
    desc1.putReference(cTID('null'), ref1);
    executeAction(cTID('slct'), desc1, DialogModes.NO);
