Stored Procedure And ExecuteReader

I am not seeing why this is not executing the reader, it just goes right by it when stepping through the code...

command.CommandType = CommandType.StoredProcedure;

// course

command.Parameters.Add( "@courseId", courseId );

// Parameter: LessonName

SqlParameter sLessonName = command.Parameters.Add( "@lessonName", SqlDbType.VarChar );

sLessonName.Size = 256;

sLessonName.Direction = ParameterDirection.Output;

// error code

SqlParameter pErrCode = command.Parameters.Add( "@errCode", SqlDbType.Int );

pErrCode.Direction = ParameterDirection.Output;

// execute the stored procedure

SqlDataReader spResults;

conn.Open();

spResults = command.ExecuteReader();

while( spResults.Read() ) // It never steps into the while statement like the reader is completed

{

RetrieveObjId objNames = new RetrieveObjId( spResults.GetString( 0 ));

searchResults.Add( objNames );

}

spResults.Close();And the stored procedure is.....CREATE  PROCEDURE dbo.retrieveLessonNames @courseId  VARCHAR(20), @lessonName  VARCHAR(256) OUTPUT, @errCode         INT               OUTPUT  ASBEGIN

 SELECT @lessonName = objName       FROM   objStructure WHERE  courseId = @courseId

 SET @errCode = 0  RETURN @errCode HANDLE_APPERR: SET @errCode = 1  RETURNHANDLE_DBERR: SET @errCode = -1  RETURNENDGOSuggestions?Thanks all,Zath
