The or formula examines other attributes at the same data class.
Format: or ( attr1, attr2, attr3.dataPoint, ... )
The formula will check the value of each argument and return the first one with a value. This is a way to compile multiple potential attributes into a single attribute.
or ( PrimaryClass.WrenchTurner, 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.
