Can you help me correct my LocalScript animation script ?

player = game.Players.LocalPlayer

local Block = player.Character.Humanoid:LoadAnimation(4819470970)
local Weaponblock = player.Character.Humanoid:LoadAnimation(4819498690)
local Weaponblockshield = player.Character.Humanoid:LoadAnimation(4819501037)
local Stance = player.Character.Humanoid:LoadAnimation(4812358432)

local m = {}

function m.PlayAnimation(anim)
	local success,err = pcall(function()
		if anim == "Block" and Block ~= nil then
			Block:Play()
		end
		if anim == "Weaponblock" and Weaponblock ~= nil then
			Weaponblock:Play()
		end
		if anim == "Weaponblockshield" and Weaponblockshield ~= nil then
			Weaponblockshield:Play()
		end
		if anim == "Stance" and Stance ~= nil then
			Stance:Play()
		end
	end)
end

function m.StopAnimation(anim)
	local success,err = pcall(function()
		if anim == "Block" and Block ~= nil then
			Block:Stop()
		end
		if anim == "Weaponblock" and Weaponblock ~= nil then
			Weaponblock:Stop()
		end
		if anim == "Weaponblockshield" and Weaponblockshield ~= nil then
			Weaponblockshield:Stop()
		end
		if anim == "Stance" and Stance ~= nil then
			Stance:Stop()
		end
	end)
end

function m.SetAnimation(anim, id)
	local success,err = pcall(function()
		if anim == "Block" then
			Block = id
		end
		if anim == "Weaponblock" then
			Weaponblock = id
		end
		if anim == "Weaponblockshield" then
			Weaponblockshield = id
		end
		if anim == "Stance" then
			Stance = id
		end
	end)
end

function m.StopAll()
	local success,err = pcall(function()
		Block:Stop()
		Weaponblock:Stop()
		Weaponblockshield:Stop()
		Stance:Stop()
	end)
end

return m

You can't put variables outside the module script table. Those variables will not work. I don't know much about ModuleScripts (yet), so that's that. Just put all the variables inside the m table. Plus, local variables that are not in a specific script scope don't need to be changed. Local Variables load faster anyway, so its better.
