I am trying to enter in a date, let's say 7/7/07 into a cell. Excel is then
taking this date and putting an = in front of this date. It is also
replacing the 07 with just a 7. I have tried formatting the cell as a date
format and the result is if 7/7/07 is keyed in, it drops the 07 for 7 and
returns 01/00/00. It is still putting the = sign in front of the numbers
like this is a formula.

I know if you put a ' in front of the date it will not do this, but I am
trying to use the date as a basis for another calculation...7/7/07-28.

Can anyone help with this? It only does this on certain spreadsheets.
