Nested IF statements

I am trying to convert an old Lotus 1-2-3 spreadsheet into Excel. I have
several cells that contain multiple nested IF statements. I understand from
the documentation that there is a limitation in Excel that says that you can
only have 7 levels of nested IF statements. I have a need to go as many as
18 levels of nested IF statements. Is there any way to cajole Excel into not
choking on this nesting? There are so many things that Excel does better
than Lotus 1-2-3, but this is one big negative for Excel. Thanks for any
input you can provide.

Hi

Another way is to use CHOOSE function, which allows up yo 24 different
choices - values or expressions. To use CHOOSE, you have to transform your
choice conditions to choice order numbers, (1, 2, ... up to 24). You can do
it p.e. using MATCH function, but sometimes simple mathematical operations
will do.

Still another way is to use VLOOKUP function with array as argument, or with
lookup table somewhere on worksheet. With VLOOKUP you are limited to values
as choices only.

I forgot to post the code for those who are willing to go back a decade or
so. The application is distributing a forecasted amount month by month (out
120 months) based on the start and end date of a project. The start and end
dates can be in the past, present or future. Because of the various
scenarios possible, we needed to compile four separate equations: month 1,
months 2 - 12, months 13 - 24, and months 25+. The equation for months 25+
converted easily (only 6 nested IF statements!) so I did not include them
here. I am aware that Excel does not have the DATEDIF function, but I can
get around that easily (only applicable for the first month anyway). Here
are the equations direct from Lotus 1-2-3:

Month 1:
@IF(L140,L14+N14,@IF((@DATEDIF(C$4,E14,"m"))1,(H 14-J14),@IF(F14T$9,0,@IF((F14-G14)=T$9,0,@IF((@DATEDIF(C$4,E14,"m"))1,(H14-J14),@IF(T$8=L$8,(L14/@IF(F14=F$1,+F14,@IF(@YEAR(@DATEVALUE(+D14))+1900 =T$8,@IF(T$9F$1,F$1,@IF(G14-F14=F$1,F$1,(13-(@MONTH(+D14))))),F$1))),@IF(T$9=F14,@IF(T$8=N$8, N14/@IF(+H14-I14-K14=N14,F14,@IF(@YEAR(@DATEVALUE(+D14))+1900=T$8,( 13-(@MONTH(+D14))),@IF(@YEAR(@DATEVALUE(+E14))+1900=T $8,(@MONTH(+E14)),@IF(F14-F$112,12,F14-F$1)))),0),0)))))))

Months 2 - 12:
@IF(L140,0,@IF(F14U$9,0,@IF((F14-G14)=U$9,@IF(F14-G14=F$1,0,0),@IF(U$8=L$8,(L14/@IF(F14G14,@IF(F14-G14+F1413,G14,G14-F14+F$1),@IF(F14=F$1,+F14,@IF(@YEAR(@DATEVALUE(+D 14))+1900=U$8,@IF(U$9=F$1,F$1,@IF(G14-F14=F$1,F$1,@IF(F$1=U$9,F$1,(13-(@MONTH(+D14)))))),F$1)))),@IF(U$9=F14,@IF(U$8=N$ 8,N14/@IF(+H14-I14-K14=N14,@IF(G14-F14F$1,F14,G14),@IF(@YEAR(@DATEVALUE(+D14))+1900= U$8,(13-(@MONTH(+D14))),@IF(@YEAR(@DATEVALUE(+E14))+1900=U $8,(@MONTH(+E14)),@IF(F14-F$112,12,F14-F$1)))),0),0)))))

Months 13 - 24:
@IF(($F14-$G14)=AF$9,0,@IF(AF$8=$L$8,($L14/@IF(@YEAR(@DATEVALUE(+$D14))+1900=AF$8,(13-(@MONTH(+$D14))),$F$1)),@IF(AF$9=$F14,@IF(AF$8=$N $8,($N14/@IF(@YEAR(@DATEVALUE(+$D14))+1900=AF$8,(13-(@MONTH(+$D14))),@IF(@YEAR(@DATEVALUE(+$E14))+1900 =AF$8,(@MONTH(+$E14)),@IF($F14-$F$112,12,$F14-$F$1)))),@IF(AF$8=$O$8,($O14/@IF(@YEAR(@DATEVALUE(+$D14))+1900=AF$8,(13-(@MONTH(+$D14))),@IF(@YEAR(@DATEVALUE(+$E14))+1900 =AF$8,(@MONTH(+$E14)),@IF($F14-$F$112,12,$F14-$F$1)))),$P14/($F14-$F$1-24))),0)))

The variables are as follows:
C$4 = Current date
D = Start month
E = Completion month
F = Months to completion from current date
F$1 = Months remaining in current year
G = Project duration
L = Projected amount for current year (N = cy+1, 0 = cy+2, etc)
L$8 = Current year
column$8 = Year of month of distribution
column$9 = # of month of distribution

Column 'T' is the first month of distribution so T$8 would be the current
year and T$9 would be 1.

Thanks for any help you can be.

Hi John

still reading through the formulas, but wanted to let you know that Excel
DOES have the Datedif function - it's just not documented - check out
http://www.cpearson.com/excel/datedif.htm
for details - seem to be giving you lots of web pages today

I have tried splitting up the equation into parts, but the results are
not consistent. See my later post to get the details of the original.

Hi again

Almost forgot another option. You can breake your nested IF() to several
independent parts. Depending the result being a number or string
=IF(condition1,result1,0)+IF(condition2,result2,0) +...+IF(conditionN,resultN
,0)
or
=IF(condition1,result1,"")&IF(condition2,result2," ")&...&IF(conditionN,resul
tN,"")

Only a single condition can be true, to make this solution to work.

Arvi:
I have posted the original 1-2-3 code in a separate post. Is it possible
to nest the 'choose' function? Because I am spreading this out over 120
months, I think I would quickly exceed the 24 choices.

If you could examine the original 1-2-3 code and give some suggestions, I
would be most appreciative.

I liked the quote 'drunk cousin' in the link! I am curious if Excel supports
the DATEDIF function and the syntax is exactly as it appears in Lotus, why
did it not convert when I brought the spreadsheet into Excel? Anyway, thanks
for the info (one less formula to convert!)

I have to leve at moment for some hours. When I return and see, that you
didn't get a passing solution jet, I'll give it a look.
