UnicodeMessage argument error

[sahisahi]

This is from ForensicEval skill.

Original code:

 if (m_Corpse.m_Forensicist != null)   
                       m_Corpse.LabelTo(m_From, 1042750, m_Corpse.m_Forensicist); // The forensicist  ~1_NAME~ has already discovered that:

My mod:

 if (m_Corpse.m_Forensicist != null)
                        m_From.Send( new UnicodeMessage( m_Corpse.Serial, m_Corpse.ItemID, MessageType.Label, 2578, 3, "", "", "The forensicist {0} has already discovered that:",m_Corpse.m_Forensicist));
