Hi, so I have a spreadsheet that I use as a timecard, and what I'd like to
do is the following.

I already have data entered in these cells as 0 so that when an employee
does not edit the field, the value is 0. My problem comes when an employee
enters the value in the wrong field. Say an employee means to enter 7 hours
in field N14. He accidentally enters the data in N13, and then deletes the
value, and enters it in N14. However, now instead of 0 in cell N13, there is
no value. What I would like to happen is to have excel automatically make
cells within a specified range default to 0 if they're data is deleted.

Any hints?
