In one step define, copy the following lines from the manual:
// Adding value
scenario_store = DataStoreFactory.scenario_datastore;
scenario_store.put("element-id", "455678");

exec gauge specs/ , error occus:

I have solved this problem, add Guage:: before DataStoreFactory. but ,I think modifying the manual http://getgauge.io/documentation/user/current/language_features/data_store.html is still necessary.
