Having problem sending vars from server side to client.

server

RegisterServerEvent('menu:characters')
AddEventHandler('menu:characters', function(callback)
  getCharacters(source, function(data)
    first = data.firstname
    last = data.lastname
  end)
end)

client

RegisterNUICallback('NUICharacters', function(data)
 TriggerServerEvent('menu:characters'', data) 
  SetNuiFocus(true, true)
  local bt = first --- Character 1(variable first from server side) ---

  SendNUIMessage({
  type = "charSelection",
  char1 = bt
})
  
end)

You got this code backwards, You should use TriggerClientEvent to pass data to the client. And adding a event handler on the clientside.

I tried it all the way around but it just returns null. Can you give me any example where u pass a variable from server to client?

Server

TriggerClientEvent('event', -1, 'Hello World!')

Client

RegisterNetEvent('event')
AddEventHandler('event', function(str)
    print('Server saids: ' .. str)
end)

Now the server will send an event to all the clients with the data “Hello World!”. If you want a specific client, pass the client source id instead of -1.
