The function you are looking for is
ISBLANK
For example in cell D4 have a cell formula
=ISBLANK(C4)
, D5 has
=ISBLANK(C5)
etc etc
Personally I would have had the validation set to
TRUE
if the data
WAS entered in which case I would have used the formula
=NOT(ISBLANK(C4))
It is very easy to get tied up with multiple isblank functions especially with localisation, dates, other formulas etc etc ... this set of search results mentions several
google search for isblank issues[
^] but I wouldn't worry about them unless/until you hit them
Finally, be careful about your terminology (so that it is easier for more people to help you out)

I have put the above columns in the excel file in the cell A and B.
. You actually meant that you have put the above
data in
rows 2 and 3 where row 1 is the headings row.
So ...
rows have numbers - usually these are displayed down the left hand side
columns have letters - usually displayed across the top of the sheet
cells are identified by their column + row e.g. C4 above.
