I am having trouble maintaining my hyperlinks when I merge PDF's. I create indices in Word first, and then I create hyperlinks to my attachments after I have converted the index to a PDF in Acrobat. When I merge two different PDF's with the indices of hyperlinks, only the links in the first PDF (the first bookmark) appear correctly. All the links from the second PDF are incorrectly directed to attachments from the first PDF. What should I do?
