I'm fascinated that you say you got it to work. I'm assuming that you've
put your formula in N5, and if so you've created a circular reference, which
has its own problems. You are testing for a text value of zero in M5, not
for a number zero.

Thanks guys, I got it to work by using
=IF(M5="0",0,N5)+((B5+C5+E5+F5)*(200000/M5)), but I like the simpler one.

I've a data gathering and calculation summary sheet in a workbook, the
other
sheets provide raw imput data.

The formula =SUM((B5+C5+E5+F5)*(200000/M5)) in N5 displays error
#DIV/0!
because M5 has a 0 valve (no problem if M5 is 1 or ). I believe IF
will
correct and display 0, but forget string. I left reference docs in home
country.
