Here's what I put together.. and it works. I can also make it say their in combat.



Code:
 local race=player:GetPlayerRace()
if race==1 or race==3 or race==4 or race==7 or race==11 then
Can't use in combat:

Code:
if (player:IsInCombat() == true) then
 player:SendAreaTriggerMessage("You are in combat, sorry!")
    else                          
  unit:GossipCreateMenu(3543, player, 0)
 local race=player:GetPlayerRace()
if race==1 or race==3 or race==4 or race==7 or race==11 then

Also a Item:

Code:
if (player:IsInCombat() == true) then
 player:SendAreaTriggerMessage("You are in combat, Sorry!")
    else                          
  item:GossipCreateMenu(3543, player, 0)
 local race=player:GetPlayerRace()
if race==1 or race==3 or race==4 or race==7 or race==11 then
