I want to make a simple gun system and it gave me this error

18:16:40.159 ServerScriptService.PistolFire:8: attempt to perform arithmetic (sub) on nil and Vector3 - Server - PistolFire:8

I’ve tried making the raycastparams different but I don’t know many options

game.ReplicatedStorage.PistolEvent.OnServerEvent:Connect(function(Player, PlayerMouse, FireTool)
	FireTool:WaitForChild("Handle").Fire:Play()
	
	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {Player.Character}
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
	
	local raycastResult = workspace:Raycast(FireTool:WaitForChild("Handle").Position, (PlayerMouse - FireTool:WaitForChild("Handle").Position)*300,raycastParams)
	
	if raycastResult then
		local Model = PlayerMouse:FindFirstAncestorOfClass("Model")
		if Model:WaitForChild("Humanoid") then
			Model.Humanoid.Health -= 25
			FireTool:WaitForChild("Handle").HitMarker:Play()
			PlayerMouse.Icon = "rbxassetid://7193947094"
			wait()
			PlayerMouse.Icon = "rbxassetid://62814275"
		end
	end
end)```

What is PlayerMouse? If it’s the mouse object, the mouse object doesn’t exist on the server, you would need to pass Mouse.Hit.Position

Ahh, thank you for the support, let me try this.

Firstly, I think you cant really get a playermouse and send to server. Because it have this following note on a player:GetMouse()

I think you need to try sending only a data from a mouse (ex. position of a mouse or mouse target) to a server
