Hey so basicaly i asked a question about 3 - 2 days ago i think but couldnt find a solution. But i did find that the reason the script didnt work was because a local script never saw that i edited a value. So i was wondering if there is anyone that knows why this happened.

Logs:

14:11:56.573  applePickupScript thinks that heal.Value = 20  -  Server
14:11:56.574  Script says that actall value is 20  -  Server - Script:2 -- The actuall value
14:11:56.591  LocalScript thinks that heal.Value = 0  -  Client - LocalScript:6 -- doesnt see the new value

applePickupScript

script.Parent.Touched:Connect(function(hit)
	
	if hit.Parent:FindFirstChild("Humanoid") then
		local player = game.Players[hit.Parent.Name]
		local audio
		
		if script.Parent.AppleQuality.Value == 1 then
			audio = hit.Parent.Head.audio1
		else
			audio = hit.Parent.Head.audio2
		end
		
		player.leaderstats.Apples.Value = player.leaderstats.Apples.Value + script.Parent.AppleQuality.Value
		audio:Play()
		
		for i, v in pairs(workspace.spawnLocations:GetChildren()) do
			if v.Position == script.Parent.Position then
				v.spotTaken.Value = false
				v.garga.Value = true
			else
				v.garga.Value = false
			end
		end
		
		game.ReplicatedStorage.heal.Value = 20 -- Updates the value
		script.Parent:Destroy()
		
	end
	
end)

LocalScript

local humanoid = game.Players.LocalPlayer.Character.Humanoid

while wait() do
	humanoid.Health = humanoid.Health + game.ReplicatedStorage.heal.Value
	if game.ReplicatedStorage.heal.Value >= 0 then game.ReplicatedStorage.heal.Value = 0 end
end

Note that the value is located in ReplicatedStorage

Thanks in advance!

Solution : I was updating a server value from a local script (see line 5 in local script) which obviosly doesnt work, so i had to create a remote that updated the value instead and run the remote in the local script. Here is the working script:

local humanoid = game.Players.LocalPlayer.Character.Humanoid

while wait() do
	humanoid.Health = humanoid.Health + game.ReplicatedStorage.heal.Value
	if game.ReplicatedStorage.heal.Value >= 1 then
		game.ReplicatedStorage.reset:FireServer(0)
	end
end

Remote :

game.ReplicatedStorage.reset.OnServerEvent:Connect(function(plr, val)
	game.ReplicatedStorage.heal.Value = val
end)
