Script vender armas

[Gaimo]

Não estou conseguindo exibir um GUI, quero que quando um jogador envie uma proposta de venda para outro, exiba um GUI na tela com as informações da venda.

Exemplo: O jogador (nome-do-jogador), está oferecendo uma (nome-da-arma) por R$ (valor).  [ACEITAR] - [RECUSAR]

Não está sendo exibido o GUI quando é feito a proposta de venda.

GUI

addEvent( "buy", true )
addEventHandler( "buy", localPlayer, function(seller, weaponID, ammo, price)
	local seller = getPlayerName(seller)
	outputChatBox("O Jogador "..seller.." esta te oferecendo uma "..getWeaponNameFromID(weaponID).. "por R$ "..price..".")
	
	local sW, sH = guiGetScreenSize()
	mainWindow = guiCreateWindow((sW-300)/2, (sH-60)/2, 600, 120, "UM NOME LEGAL", false)
	guiWindowSetMovable(mainWindow, false)
	guiWindowSetSizable(mainWindow, false)

	bt_accept = guiCreateButton(10, 80, 80, 30, "ACEITAR", false, mainWindow)
	guiSetProperty(bt_accept, "NormalTextColour", "FF14EA37")
	text = guiCreateLabel(53, 27, 494, 28, "O Jogador "..seller.." esta te oferecendo uma "..getWeaponNameFromID(weaponID).. "por R$ "..price..".", false, mainWindow)
	bt_cancel = guiCreateButton(510, 80, 80, 30, "RECUSAR", false, mainWindow)
	guiSetProperty(bt_cancel, "NormalTextColour", "FFFD0000")  
end)

 

 

 

Esse é o evento que está no servidor:

  Reveal hidden contents

addEvent("sellWeapon",true)
addEventHandler("sellWeapon",root,
	function(buyer, weaponID, ammo, price)
		--               seller = source
		triggerClientEvent(buyer, "comprar", source, weaponID, ammo, price)
	end
)

 

e é assim que estou chamando o evento: 
triggerServerEvent("sellWeapon",localPlayer,player,WeaponID,Ammo,900)   -- 900 é o price.

Código todo do client:
