Thanks Paul,

What a pleasant surprise that you responded. Given that the thread was a few years old, and showed 'solved' I wasn't sure if anyone would.

The problem is that it isn't a form, it is a very long document, and many of the text strings throughout the document are not yet form fields. Since there are hundreds of instances of each string, it would take a long time to manually go through and replace them with the cross-references. So I was thinking about whether its possible to automatically create the form fields and populate the data throughout the document.
