DataHolder in AS2.0: A simple question

Ok, I’ve created an DataHolder object instance named dhData. It has a schema set up like:

<-> data:Object[indent]<->id:Number

<->name:String
<->value:String

[/indent]And a text field is bound to the value of id, whose default value is 1. Binding is working just how I wanted it. But now I have some code that I want to change the value of id. I thought I could assign a value by using either dhData.id or _root.dhData.id, but neither works… they both are undefined. This seems like it should have a simple answer, but I can’t seem to find any detailed help using code with a DataHolder object from the web or any of my 4 Flash/Actionscript books.

Little help?
