Script isn't changing a value when a player joins?

I have a script that changes a value inside of replicated storage when a player joins or leaves. Here is my script:

wait(1)
local Players = game:GetService("Players") --gets players
local value = script.Parent.PlayersOnline
local PlayerCount = #Players:GetPlayers() --gets the amount of players

Players.PlayerAdded:Connect(function() --if a player gets added,
    PlayerCount = PlayerCount + 1 --increase the playercount by 1
	value.Value = PlayerCount
end)
 
Players.PlayerRemoving:Connect(function() --if a player gets removed,
	PlayerCount = PlayerCount - 1 --decrease the playercount by 1
	value.Value = PlayerCount
end)

When someone joins, the value doesn't change for some reason. Any suggestions?

If you're testing in Play Solo mode in Roblox Studio, sometimes the player loads too fast and the event isn't fired. To fix it, either create a proper local server or add a function to the event and loop through the players to not miss any of them. Example:

function onPlayerAdded(player)
--Codes here
end

for _, player in pairs(game.Players:GetPlayers()) do --looping through the players list
	onPlayerAdded(player)
end

game.Players.PlayerAdded:Connect(onPlayerAdded) -- attaching the function to the event

For the PlayerRemoving event, you can also do the same.
