Thanks for that. That is a good idea and I will keep it in mind.

Not to go into too much detail, but my report gives 4 cuts of the same data. So its sorted by Month / Offices / Department&Owner / Product / Corporate Customer.

There is just no way to do all the calcs in the SQL (As you can't sum or average the percents)

So can I take it then there is no easy OnError Display 0.
