Date Values Changing Rows

[kr 87]

We have a shared workbook, and one of the worksheets always changes date
values. For example, we have columns that list people's birthdays, address,
driver's license expiration, etc., but the columns with date values will
change to other rows. Like one person's birthdate will move down to someone
else's row. None of the other information does this, only columns with
dates, and it is only one of our worksheets that does this. The others have
similiar info but the dates save just fine. Can anyone shed some light on
this problem?

I am not doing any manipulation to the dates, there are formulas in other
colums of the spreadsheet, but not in any of the date columns. I will
attempt to create a workbook that exhibits the behavior and post it on here.
Thanks for your input!
