Try =IF(D550,IF(E17=1,IF(D13<36.344,1,IF(D13<39.549,2 ,3)),0),0)

I assume you want it to return 0 if D55<=0, or if E17<1?

You said:
" Next, if cell E17=1 AND if D13<36.344, then I want a value of 1 returned.
IF(D13<36.344,1

BUT... (still assuming that E17=1) if D13=36.344 or D13<39.549, I want a
value of 2 returned."
but in that case if you haven't satisfied the test for D13<36.344 then it
must satify the test for D13=36.344, so I assume that you nean AND
D13<39.549, rather than OR D13<39.549?

I am trying to return certain values if certain criteria are met. Here is
my
function, and I will break it down to make this easier to understand:

=IF(D550,IF(E17=1,IF(D13<36.344,1,IF(D13=36.344, OR(IF(D13<39.549,2,IF(D13=39.549,3,0)))))),0)

First, this cell will only display if D550, hence
=IF(D550,

Next, if cell E17=1 AND if D13<36.344, then I want a value of 1 returned.
IF(D13<36.344,1

BUT... (still assuming that E17=1) if D13=36.344 or D13<39.549, I want a
value of 2 returned.
IF(D13=36.344,OR(IF(D13<39.549,2

and lastly (and still assuming that E17=1), if D13=39.549, I want a value
of 3 returned.
IF(D13=39.549,3

And to close out the function...
,0)))))),0)

What I am getting with this current function is that if I type a number in
D13 that is < 36.344, I get a correct value of 1 returned. However, if I
have a number that is = 36.344 in D13, all I get is a "True" value
returned
and I can't figure out why.

Please forgive me if this is not possible; I am pretty new at TRYING to
understand multiple function Excel programming, and being an old BASIC
programmer seems to be a detriment....
