you never told us which lines contains the errors. Why have you got your OnPlayerSelectedMenuRow callback inside the OnPlayerExitedMenuRow callback? To make it worse, inside OnPlayerSelectedMenuRow you have a /smgDM command.

Take the /smgDM out of there and place it under OnPlayerCommandText. Also take out OnPlayerSelectedMenuRow out of OnPlayerExitedMenuRow.

Good luck.
