In addition to what Bob said, you also need to verify you match the return type. In your code above you are asking for a dataset as the return type. Therefor your method signature would look like this.

public DataSet GetCrewByCrewID(int crewId)
Typically you would return either a CrewEntity or a mmBindingList<CrewEntity> like this.

public CrewEntity GetCrewByCrewID(int crewID)

or an entity list like this
public mmBindingList<CrewEntity> GetCrewByCrewID(int crewID)

It is a matter of wether you are returning a single row or multiple rows.

I hope that helps
Tim
