I add or change information to various cells in my copy of the spreadsheet [S1] and then send it to Pat via email. Pat has been adding or changing information to her copy [S2] of the same spreadsheet . When she receives the email with my copy of the spreadsheet attached [S1], she saves it and her computer asks her if she wants to replace the current file [S2] with the one she just got from me [S1] because they have the same name . If she says no, then nothing happens. If she says yes, then her copy [S2] is deleted and replaced by my copy [S1] eliminating anything on [S2] that was not already on [S1] which effectively means all the changes she made to the spreadsheet are gone. We are not on the same network which is why changes made by one of us does not show up in the other one's copy. Is there a way to just update the spreadsheet with just the changes?
