Thanks for your help, Charles. Ultimately, I want to create a pdf from this form. Would the submit Mailto: still function?

That is actually a hyperlink.

It may or may not be preserved in the pdf; this would depend on how you save the pdf.
If you have a pdf editor, which you would really nead to create a fillable pdf form, you can do this in that editor. Word would just give you the framework or backdrop.
