Hi!
I need to get an Average from several columns, if from several columns there is the same value.
Eg: I have 10 columns with duration type, and other 10 columns with email USER, I need to get the AVERAGE time of each user.
I know how to do it from a single column, but not from several columns.
Any thoughts ?
