So what you can do is in replicated storage add in a remote event called 'Joined and in serverscript servcie add in a normal script then check when the player joins with game.Players.PlayerAdded:Connect(function(player) game.ReplicatedStorage.Joined:FireClient(player) end)
then in a local script in screen gui do
game.ReplicatedStorage.Joined.OnClientEvent:Connect(function()
local TextLabel = script.Parent.Frame
TextLabel.BackgroundTransparency = 1
TextLabel.Text = "Loading"
TextLabel.TextScaled = true
task.wait(5)
for index=0.1,1,1 do
TextLabel.BackgroundTransparency = index
task.wait(0.01)
end
task.wait(1.75)
print("Loaded.")
local days = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}
print("Today is " .. days[5])
end)
this should work I think
