Try this,

I added in the proper code at the bottom. But if that doesn't work you should trying changing textid -->pUnit:GossipCreateMenu(3543, player, 0) to something else, like 100 just to test. Sometimes for certain text_id's gossip npc's bug out. No clue why (Might just happen on my server too)
