To parent clientCmdChatMessage you'd want parent::clientCmdChatMessage(%a,%b,%c,%fmsg,%cp,%name,%cs,%msg);
To parent NMH_Type::send you'd want parent::send(%this);
It depends which one you're using, it appears you're using clientCmdChatMessage but before you edited that in you were using NMH_Type::send, so I have no idea what you're doing.
For fixing the syntax error, see my post above yours.
