+ rep for some asistance

[TheSpidey]

Please man, indent your code and keep a well defined structure.

[thijsd]

The mage link u added, is redirecting to case 9,

where is this code:

 case 9:
objmgr.CreateGossipMenuForPlayer(&Menu, pCreature->GetGUID(), 1, Plr);
Menu->AddItem(0, "[Back]", 99);
Menu->SendTo(Plr);
break;

so thats where u need to put your mage code, but theres alreay a code there.
What u always can do, is looking where the script is used in the game, and just copy it
