Help with Headers
 

We have a shared workbook on a network which is being accessed by two users.
The workbook is not saved on either of the two computers who are accessing
it. All of the changes that are being made in the workbook are being saved
correctly so that each of the users sees the same changes. However, when one
user changed and saved the header (file, page setup, header/footer tab) it
did not show up on the other users computer. The header that was used prior
to the save showed up. When both users open the file at the same time, they
see different headers. How can one Excel file have two different headers? We
have saved the print screen showing the two different headers in the file,
but cannot attach it to this post.
