so I have a script I partly wrote with some help form youtube and websites, Its a server side stamina script (there is a reason to why I'm using a server side instead of local) Ill try my best to say where the scripts are located

In Replicated storage I have two events Sprint and StaminaUpdate

the Stamina client is located in: StarterPlayer StarterCharacterScripts local script

local userInputService = game:GetService("UserInputService")
local replicatedStorage = game:GetService("ReplicatedStorage")
local players = game:GetService("Players")

-- Sprint Key Pressed
userInputService.InputBegan:Connect(function(input)
	if input.KeyCode ==Enum.KeyCode.LeftShift then
		replicatedStorage.RemoteEvents.Sprint:FireServer("Began")	
		wait(0.01)
		replicatedStorage.RemoteEvents.Sprint:FireServer("Ended")	
	end
end)

-- Sprint Key Pressed
userInputService.InputBegan:Connect(function(input)
	if input.KeyCode ==Enum.KeyCode.LeftShift then
		replicatedStorage.RemoteEvents.Sprint:FireServer("Ended")
	end
end)

replicatedStorage.RemoteEvents.StaminaUpdate.OnClientEvent:Connect(function(stamina, maxStamina)
	players.LocalPlayer.PlayerGui.Hud.StaminaBar.Stamina.Size = UDim2.new((stamina / maxStamina) * 0.98, 0, 0, 10)
end)

I also then have the Stamina Server script in: ServerScriptService

local replicatedStorage = game:GetService("ReplicatedStorage")
local players = game:GetService("Players")
local runService = game:GetService("RunService")

local maxStamina = 500
local staminaRegen = 2
local minStamina = 0

local sprintModifier = 1.8
local sprintStaminaCost = 5

local sprintingPlayers = { }

players.PlayerAdded:Connect (function(player)
	local stamina = Instance.new("IntValue", player)
	stamina.Value = maxStamina
	stamina.Name = "Stamina"
	
	stamina.Changed:Connect(function(property)
		replicatedStorage.RemoteEvents.StaminaUpdate:FireClient(player, stamina.Value, maxStamina)
	end)
end)


-- Adjust Stamina for each player every frame
runService.Heartbeat:Connect(function()
	for index, player in pairs (players:GetChildren() ) do
		local stamina = player.Stamina
		local name = player.Name

		
		if sprintingPlayers[name] then
			if stamina.Value > maxStamina or
				stamina.Value <= maxStamina - 500 then
				stamina.Value = 0
				
			elseif stamina.Value < maxStamina then
				stamina.Value = stamina.Value - staminaRegen
				
		else
				if stamina.Value >= sprintStaminaCost then
					stamina.Value = stamina.Value - sprintStaminaCost
				else
					player.Character.Humanoid.WalkSpeed = sprintingPlayers[name]
					sprintingPlayers[name] = nil
				end	
			end
		end
	end
end)

-- sprint key is pressed or released
replicatedStorage.RemoteEvents.Sprint.OnServerEvent:Connect (function(player, state)
	local humanoid = player.Character.Humanoid
	local stamina = player.Stamina
	
		if state == "Began" and humanoid:GetState ()  ==  Enum.HumanoidStateType.RunningNoPhysics and humanoid.MoveDirection.Magnitude > 0 and stamina.Value > minStamina then
			sprintingPlayers [player.Name] = humanoid.WalkSpeed
			humanoid.WalkSpeed = humanoid.WalkSpeed * sprintModifier
		
		elseif state == "Ended" and sprintingPlayers[player.Name] or stamina.Value < minStamina then
			humanoid.WalkSpeed = sprintingPlayers[player.Name]		
			sprintingPlayers[player.Name] = nil
		end
end)

So I think my issue is with the last part of the Stamina Server, I've realized that its hanging on the if statement, I have no idea on how to check every frame if the player has enough stamina to be able to run.

Any help is much appropriated :D and just say if you need me to explain anything more.
