I'm trying to make trigger event from client to client but not working

Hello guys im fetching vip status like yes or not and vipskin model from database its ok i get these 2 variable.But then im trying to trigger a eventhandler on skinchanger and then define variables there.But seems like its not sending variables do there and not working where is problem in my code?

On the top of script i define these local vippy and local model and then

ESX.TriggerServerCallback('esx_skin:getPlayervip', function(vipstatus, vipmodel)
	
		   if vipstatus then	    
			 vippy = true
			 model = vipmodel		 
			 end		
 
	TriggerEvent('skinchanger:vipskin', vippy, model)
			end)

Trying to define variables in skinchanger

RegisterNetEvent('skinchanger:vipskin')
AddEventHandler('skinchanger:vipskin', function(vip, vipmodel)


	if vip then
	
	vipcheck = true	
	vipskin = vipmodel
   
	end
	
end)

of course there is vipcheck=true and vipskin=’ ’ on top of page

but my code still not running like it can’t get vipskin data but its getting vip if true or not

Sorry for bad english.
