Need to show form data in multiple places

I just started using the forms module. I know that pdf allows information entered in once field to be shown in multiple locations, like the bureaucratic forms that require the same information (e.g., name, id#) to be entered on each page. I've been unable to discover how to accomplish this using 6.0 after a couple of hours trying, but know there should be some simple method I'm missing.

Hi,

the proper way to do this would be using JavaScript for PDF to insert the same value into multiple fields.
It seems to be possible to achieve the same goal by giving all form fields which are supposed to have the same value the same name in their properties, but I am not sure if this has any unwanted side effects.

Best regards

Robin
