Word Macro to Search & Replace within an Textbox

Hi-
I've recorded a Word (2003) macro to do a simple search/replace in a word doc. The problem is that it can not "see" text that resides in a textbox on the first page of my doc. It's also having a problem detecting words in the header.
Search/Replace without recording seems to work fine... it's just trying to capture the same steps in a Macro I'm having trouble with.

Any assistance would be greatly appreciated.
