Literally.

An error occurs in the “local lookAt = (targetPos - Character.Head.Position).unit” section. The error message looks like this. Please help me

Remote.OnServerEvent:Connect(function(player, mousePosition)

	local targetPos = mousePosition.p
	local lookAt = (targetPos - Character.Head.Position).unit
	Toss(lookAt)
	LeftDown = true

I have the solution of your problem:

Remote.OnServerEvent:Connect(function(player, mousePosition)
	if not AttackAble then return end
	AttackAble = false
    local Character = player.Character or player.CharacterAdded:Wait()
	if Humanoid and Humanoid.RigType == Enum.HumanoidRigType.R15 then
		Remote:FireClient(getPlayer(), "PlayAnimation", "Animation")
	end
	local targetPos = mousePosition.p
	local lookAt = (targetPos - Character.Head.Position).unit
	Toss(lookAt)
	LeftDown = true
end)

Character index doesn’t seem to be an issue.

Please remove the parenthesis from getPlayer.

This Variable is likely to be your issue.

I see, you can replace getPlayer() to player

Remote.OnServerEvent:Connect(function(player, mousePosition)
	if not AttackAble then return end
	AttackAble = false
    local Character = player.Character or player.CharacterAdded:Wait()
	if Humanoid and Humanoid.RigType == Enum.HumanoidRigType.R15 then
		Remote:FireClient(player, "PlayAnimation", "Animation")
	end
	local targetPos = mousePosition.p
	local lookAt = (targetPos - Character.Head.Position).unit
	Toss(lookAt)
	LeftDown = true
end)

How do you define the mouse position?
