I have presumed Y and N are the only options with my
previous answer, you
could add another IF function to check for blanks or non
entry of N or Y,
like so

=IF(A1="Y",SUM(B1:D1)-E1,IF(A1="N",SUM(B1:D1),IF
(A1="","","Error")))

Is is possible to make a letter in a cell trigger an
equation. For example, if in a cell I put the letter "Y"
(for yes) it will add a group of cells then sugtract a
value from another cell to give me a total. But if I
enter
the letter "N" (for no) then it will only add a group of
cells to give me a total without subtracting a value as
it
did before?

Thanks,
