Fill a cell based on a condition being met

[confused teacher]

Hi, I am trying to develop a formula that will only fill the final grade of a
student in the event that there are two grades allocated in the results
column. I have the formula to assign the letter grade worked out, but because
the value of the source cell is '0', Excel automatically assigns a 'F' in the
cell (B13) (and rightly so as the formula is simply doing what it is told).

I have 2 seperate scores, one each stored in cells D13 and E13, these are
summed to give a total score out of 100 and this result is stored in cell
C13. Based on the following formula :
=IF(C13>84.99,"HD",IF(C13>74.99,"D",IF(C13>64.99,"C",IF(C13>49.99,"P",IF(C13>42.99,"PC",IF(O7>=0,"F"))))))

I need the result in the format of a letter grade in cell B13 based on the
formula above, however I only want a value displayed in cell B13 if the
criteria below is met:

A grade is assigned in each of cells D13 and E13.

If anyone has an answer it would be greatly appreciated.

Hi!

If I understand correctly:

=IF(COUNTA(D13:E13)<2,"",IF(AND(ISNUMBER(O7),O7<43),"F",LOOKUP(C13,{43;50;65;75;85},{"PC";"P";"C";"D";"HD"})))

Thanks Biff, it works.
You dont happen to know how to get a formula to copy down automatically when
you enter new data in the cell. I have a cohort of students and the numbers
vary considerably, it would be so much easier if i could just enter the raw
data and the formulas copied down as necessary.

thanks Brian

The only way I know of is to "key" the formula on a certain cell. If that
"key" cell has data entered into it then the formula does its thing but
until the key cell is filled, the formula returns a blank.

That would mean you'd have to copy the formula beyond the current end of
data in anticipation of future data entry.

It's simple enough, just another IF:

=IF(A1="","",do_this_when_A1_is_filled)
