is that the order you want them in
What happens if both F4 and H4 are blank ?
Also if the SUM(E4:I4 = E12 what do you want ?
A Nested IF will work left to right in order , so i have done in your order apart from the
but IF E4="" , give E12-F4
I have put that first
IF( E4="" , E12-F4 , IF (sum(E4:I4)<E12, E12-SUM(E4:I4) , IF (SUM(E4:I4)>E12, E12-E4, IF( F4="", E12-G4 , IF (G4="", E12-H4, IF (H4="", E12-I4, "What to do if none match"))))))
=IF(E4="",E12-F4,IF(SUM(E4:I4)<E12,E12-SUM(E4:I4),IF(SUM(E4:I4)>E12,E12-E4,IF(F4="",E12-G4,IF(G4="",E12-H4,IF(H4="",E12-I4,"What to do if none match"))))))
BUT i suspect this may not be the result you want
Note: Images are difficult to see , and also requires that I input all the data myself, which is very time consuming.
A SMALL sample spreadsheet, around 10-20 rows, would help a lot here, with all sensitive data removed, and expected results mocked up and manually entered, with a few notes of explanation.

OR if you cannot get XL2BB to work, or have restrictions on your PC , then put the sample spreadsheet onto a share
I only tend to goto OneDrive, Dropbox or google docs , as I'm never certain of other random share sites and possible virus.
