formula to enter data into a blank cell

[NateM]

Does anyone know of a formula that will put a value into a blank cell? So far
it seems that all of excels formulas look at values and conditions of a cell.
It seems none put a value into a blank cell.

Background for the question:
I've created a calendar to track vacation time spent in a given year using
excel. Each day of the calendar is made up of 2 cells (one on top of the
other). The top cell for the day contains the date. The bottom cell the user
will enter either a 'V' for vacation or 'S' for sick time.
So far I have the calendar setup so that when I change the year excel will
automatically change the calendar's days and dates to make them accuate for
the given year.
I want to add a piece that will fill the bottom cells with an 'H' for the
company "approved" holidays. I know I could put a formula into all the cells
of the calendar that would check the date against a list of Holidays and fill
the cell with an 'H'. The problem is I need the bottom cells to be blank so
that the users know those cells are for data enty.

How about using conditional formatting to highlight the cells that are
holidays?

Hi,

You could apply conditional formatting such that the holiday cells are
"greyed out" if they match the dates on the holiday list.
