Merge fields in a document with a watermark

I created a document that has our company logo as the watermark centered on
the page. I then typed the document with merge fields placed where needed
(merge fields are coming from an Access database that we use). When I test
the procedure in Word it works without fail but when I move the word document
into the Access database so the fields merge it fails. So after several
attempts I removed the watermark and low and behold it worked. Add the
watermark back and it fails. Is there anything I can do to get around
this?????
