Error Code 0006

Hi,
after saving the first question i got this error:

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ ‘appelez ‘, 1, ‘appelles’, 0, ”, 0, ”, 0, ”, 0, 2, ”, ‘1’, ”, 1, ‘0’, 0)’ at line 1]
INSERT INTO nsz353u1ke_mlw_questions (question_id, quiz_id, question_name, answer_one, answer_one_points, answer_two, answer_two_points, answer_three, answer_three_points, answer_four, answer_four_points, answer_five, answer_five_points, answer_six, answer_six_points, correct_answer, question_answer_info, comments, hints, question_order, question_type, deleted) VALUES (NULL , 1, ‘1. Vous vous ____________ comment ?’ , ‘apelez’, , ‘appelez ‘, 1, ‘appelles’, 0, ”, 0, ”, 0, ”, 0, 2, ”, ‘1’, ”, 1, ‘0’, 0)

And your message: Uh-Oh! There has been an error in this action! Please share this with the developer: Error Code 0006

Something to worry about?
