Made a steps leaderboard, says input is a nil value, any help?

I tried making a game that gives you points for walking. It does not work, because 'input' is a nil value in the server script. Here's the script:

LocalScript (in StarterGui):

local uis = game:GetService("UserInputService")
uis.InputBegan:connect(function(input)
	game.ReplicatedStorage.addValueToSteps:FireServer(input)
end)

Server Script (in ServerScriptService):

game.ReplicatedStorage.addValueToSteps.OnServerEvent:Connect(function(client, input)
	if input.KeyCode == Enum.KeyCode.A or Enum.KeyCode.S or Enum.KeyCode.W or Enum.KeyCode.D then 
		local steps = client.leaderstats.Steps 
		local char = client:FindFirstChild("Character") 
		if char then
			local walkSpeed = char.Humanoid.WalkSpeed
			steps.Value = steps.Value + walkSpeed / 10
		end
	end
end)

The problem is that it is stating that, on line 2, the 'input' parameter in the server script equals a nil value. What is happening with this?

Hi!

The way you are making this is not correct. The "input" value will return nil because the input have to be defined inside the InputBegan function. Here is how your script have to be like:

LocalScript

local uis = game:GetService("UserInputService")

uis.InputBegan:connect(function(input)
	if input.KeyCode == Enum.KeyCode.A or Enum.KeyCode.S or Enum.KeyCode.W or Enum.KeyCode.D then
    	game.ReplicatedStorage.addValueToSteps:FireServer(input)
	end
end)

ServerScript

game.ReplicatedStorage.addValueToSteps.OnServerEvent:Connect(function(client)
	local steps = client.leaderstats.Steps 
	local char = client:FindFirstChild("Character") 
	if char then
		local walkSpeed = char.Humanoid.WalkSpeed
		steps.Value = steps.Value + walkSpeed / 10
	end
end)

I hope this works for you!
