At the start of this formula, I want to add a 7th IF statement that checks
the condition of another cell, and sets this whole formula to "--" if the
other cell is "". When I try to add it, I get a standard formula error
message box, and then the last MAX is highlighted. What's going on?
=IF((AND((X2+Y2)=MAX((X2+Y2),(AF2+AG2),(AN2+AO2),( AT2+AU2),(AZ2+BA2),(BF2+BG2)),(X2+Y2)=BQ2),V6,IF
{and so on five more times, checking next AF+AG. The formula ends with: if
false, "--". (I have left out the $ before each cell reference for brevity.
The entire formula is about 700 to 900 characters long, depending how far
down the sheet it is, but I can't add the 7th IF statement to even the
shortest one.) What prompted the need for the 7th if statement is
that without the underlying data cells being filled in, a #VALUE! error is
reported. Cells X,Y,AF,AG, etc. are themselves formulas, and are set to
equal "" when the underlying data are absent. I have two other formulas very
similar to this one, one checking just X,AF,AN, etc, and the other checking
Y, AG,AO, etc. They don't report the error message. Only the formula with
the combined X+Y, AF+AG, etc is a problem. There is also another combined
X+Y, AF+AG, etc formula showing the same error message, but it only has 3 IF
statments, and I am able to add the beginning 4th to cure the problem.

Thanks in advance for any help

Hello:

You hit the limit of nested if's. From the Excel help file:

Nesting level limits A formula can contain up to seven levels of nested functions. When
Function B is used as an argument in Function A, Function B is a second-level function. For
instance, the AVERAGE function and the SUM function are both second-level functions because
they are arguments of the IF function. A function nested within the AVERAGE function would be
a third-level function, and so on.

Don't worry about brevity. Post your entire actual working formulas as
plain text. If you mean you're checking whether each of the X+Y, AF+AG,
AN+AO, etc. values equals the maximum of all such values, you don't
need multiple IFs. You could use a lookup.

=INDEX(V6*{1;0;0;0;0;0}+AL6*{0;1;0;0;0;0}+...,MATC H(MAX(X2+Y2,AF2+AG2,...),
(X2+Y2)*{1;0;0;0;0;0}+(AF2+AG2)*{0;1;0;0;0;0}+..., 0))

which can easily be modified to

=IF(A1="","--",INDEX(...))

that without the underlying data cells being filled in, a #VALUE! error is
reported. Cells X,Y,AF,AG, etc. are themselves formulas, and are set to
equal "" when the underlying data are absent. . . .
....

If these cells could be "", then using them as arithmetic operands will
generate #VALUE! errors. If they should be treated as zeros, why not
set them to 0 rather than ""? Alternatively, wrap them inside N()
calls, e.g.,

=IF(A1="","--",INDEX(N(V6)*{1;0;0;0;0;0}+N(AL6)*{0;1;0;0;0;0}+. ..,
MATCH(MAX(N(X2)+N(Y2),N(AF2)+N(AG2),...),(N(X2)+N( Y2))*{1;0;0;0;0;0}
+(N(AF2)+N(AG2))*{0;1;0;0;0;0}+...,0))

I'm aware of the seven level limit. The formula had six levels, and it won't
accept the seventh. That is what is frustrating me.

It might be worth seeing what happens if you remove some of the other
brackets which may not be needed, such as where you've got (X2+Y2)
and(AF2+AG2), etc. Hopefully those expressions don't need brackets.

OK, so I did guess what you were trying to do: find the maximum sum of
pairs of cells in nonadjacent ranges and return a corresponding value
but also check that these cells sum to something greater than some
other cell.

Your ranges are uniformly spaced, every 6 columns, so take advantage of
that.

Try the array formula

=IF(MAX(IF(MOD(COLUMN($V6:$BD6)-COLUMN($V6),6)=0,$X2:$BF2+$Y2:$BG2))=
BQ$2,INDEX($V6:$BD6,MATCH(MAX($X2+$Y2,$AF2+$AG2,$A N2+$AO2,
$AT2+$AU2,$AZ2+$BA2,$BF2+$BG2),IF(MOD(COLUMN($V6:$ BD6)-COLUMN($V6),6)
=0,$X2:$BF2+$Y2:$BG2),0)),"--")
