sum numbers only when a named cell is not zero
 

In my spreadsheet, I need cell L10 to sum cells ( M10-P10) if P10 does not
equal zero. P10 is a formula=+n10+O10.

Cheryl,

try

=if($P$10<0,sum(M10:P10),"")

or

=if($P$10<0,sum(M10:P10),0)

to reflect a zero.

One way:

=IF(P10<0,SUM(M10:P10),"")

Given P10's formula, it could also be

=IF(P10<0, 2*P10+M10,"")

or, if you want to return 0 instead of a null string:

=(P10<0)*(2*P10+M10)


Note that the first "+" in your formula is superfluous.
