Win XP; Office 2003

Paste formula from linked files. This is the command I'm using: on the
destination file; highlighted the cell with the formula -- click on the
copy icon -- place cursor on upper left of cell, then drag to the other
cell locations -- select the down arrow next to the paste icon -- paste
special, select the formula and transpose boxes.

This works great! It increments the formula ie. C1 to C2 etc. and the
value of the source file is shown. However, when forwarding the files to
someone else; she has the validation tool come up and needs to browse to the
source file. How can I remove that? I have not protected the sheet...

Thanks
