Div / 0

[Chris]

Hello all
How can I get this formula to not return Div/0.
N32=N34-Sum((P39/E52)+(P41/C32)+(P43/16.9)+N30)+P45/16.9
It works ok so long as one of either P39, P41, P43, P45 has a value greater
than 0.
If all are "0" then it returns Div/0. if all are "0" the I need N32 to =
N34-N30
I hope you can follow this so you can help. ???????

Thanks
Chris

Hi
=if(iserror(N32=N34-Sum((P39/E52)+(P41/C32)+(P43/16.9)+N30)+P45/16.9),N34-N30,N32=N34-Sum((P39/E52)+(P41/C32)+(P43/16.9)+N30)+P45/16.9)

N32=N34
-Sum((P39/E52)+(P41/C32)+(P43/16.9)+N30)
+P45/16.9 [....]
If all are "0" then it returns Div/0. if all are "0" the
I need N32 to = N34-N30

I suspect you want:

=N34
- (if(E52=0,0,P39/E52)
+ if(C32=0,0,P41/C32) + P43/16.9 + N30)
+ P45/16.9

Note the absence of the use of SUM. It was superfluous in your case.

Also note that the formula can be made a little more readable by applying
some basic math to simplify it, to wit:

=N34
- if(E52=0,0,P39/E52)
- if(C32=0,0,P41/C32)
- P43/16.9 - N30 + P45/16.9

You can one step further:

=N34
- if(E52=0,0,P39/E52)
- if(C32=0,0,P41/C32)
- N30 + (P45-P43)/16.9

Actually it's C32 and E52 who are that dasterdly deed doers!
This should work in N32...

=IF(OR(E52=0,C32=0),N34-N30,N34-SUM((P39/E52)+(P41/C32)+(P43/16.9)+N30)+P45/16.9)

Chris,

It's C32 & E32 that must be populated for the formula to work, try this.

=IF(COUNT(C32,E52)=2,N34-SUM((P39/E52)+(P41/C32)+(P43/16.9)+N30)+P45/16.9,"")

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

And to make it easier to follow, get rid of the unneeded Sum function and
parentheses:
=IF(COUNT(C32,E52)=2,N34-P39/E52+P41/C32+P43/16.9+N30+P45/16.9,"")
