In Excel, with the following function:
=IF(AND(N3=1,ISNUMBER(D3),ISNUMBER(E3)),SUM(D3:E3)-2,IF(AND(N3=1,D3="",E3=""),G3,IF(N3=1,"",IF(AND(N3=0,ISNUMBER(D3)),D3-1,IF(AND(N3=0,ISNUMBER(E3)),E3-1,IF(AND(N3=0,D3="",E3=""),G3,IF(N3="","",G3)))))))
I get the error:
Formula omits adjacent cells
How can I fix the formula to avoid getting the error?
The error you are getting means that there are cells near the ones in your formula that are of a similar format and Excel thinks that you might have missed them by accident. For example, if you had
A
1 87
2 76
3 109
4 65
then the formula
=SUM(A1:A3)
would give a similar error. So, without seeing your source data, it is difficult to answer your question. I would recommend updating the formula as it suggests and then seeing if it then includes all the cells you want. If it doesn't, just undo and ignore the error.
