The summarize formula looks at the data one level down and creates a summary of counts on the parent.
summarize ( attrName ) or summarize( attrName.dataPoint )
The resulting value is NOT usable as a badge on its own, rather, it is a pre-req for the count function.
summarize ( StormRole )
summarize ( StormRole.Qualified )
The formula, attribute name and data point must be spelled and in the same case as the formula, attribute or data point you are referencing.
E.g. If an attribute is called CrewType, in the formula, you must use CrewType. crewType and CREWTYPE will not reference the CrewType attribute.
