I've a fairly long list of values from which I want to determine average values for a set of related values.
In the attached, the AverageIfs formula works fine until it gets to 115 matching; then from 117 onwards I get a Divide/0 error. I think all the cells have number values (not text) and there are no zero values so I'm confused as to why it stops working.
Any help is greatly appreciated!
