Hi Guys

I am currently using office 2007
I have a large spreadsheet that uses the following formula:

=IF(G5/51,F5/g5,g5/f5)

This produces a "div/0" error from time to time when the values in G5 & F5
are 0
I have been trying to use iferror to resolve this to report 0 but keep
getting an error message suggesting either a problem with the formula or
not
enough arguments etc....

Any suggestions as to the correct formula ?

thanks
Roy
