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.
