Check that against the round, age group and bow class there is a valid lookup value. 

Lookup values connect rounds, bow classes and age groups to the handicap and classification tables (GB).  This ensures that whatever name is given to an age group, bow class or round handicap and classification values will be returned. If no lookup value is set then no values will be returned.  

If the wrong lookup value is set the wrong values will be returned. 

Example: Round name Barebow @ 50m on 122cm Face.  This round does not exist with this name in the official tables so no values can be returned.  The values in the tables are listed against WA50m (122cm Face).  Providing the round  Barebow @ 50m on 122cm Face with the lookup value WA50m (122cm Face) enables handicap and classification values to be returned for the round.
