=SUM(IF(NOT(ISERROR(y4:y204)),y4:y204))
array entered (ctrl+shift+enter)
will exclude all entries which have any errors (N/A#,Div# etc) and sum the
rest

i have a colomn where each line has uses the formula
=IF(V4=0,SUM(E4/D4*X4),SUM(W4/V4*X4))
at the bottom i am trying to sum the answers
=sum(y4:y204) but some of the lines return #div/0! because there is no
data on that line.

?How do you tell the sum to exclude the #div/0! errors and sum the others
to
get a total????

thanks in advance
