'Statistics' error

[EXG133]

I'm trying to create some reports. I haven't found a good manual so I'm stuck. I get the following result:


Incident State - Location::Type,"TVM"
Incident - Station,"You must define a class in one axis."
Operational - Station,"You must define a class in one axis."
Warning - Station,"You must define a class in one axis."

Code: Select all

  </UseAsXvalue>

Or if anyone has a good how-to / manual for the statistics part I'm willing to try again tomorrow
