How can I copy a string from my exel document to a text box on a form in a
word document?

I can open the word document with the following:

Dim appWD As Word.Application
Set appWD = CreateObject("Word.Application")
appWD.Documents.Open Filename:=strPath & "\Letter.dot"

I just dont know how to refence the text box to then make it equal to the
string.

Thanks for your help in advance.
