Im trying to loop the mouse position through fe but im having trouble what im trying to achieve is this through fe ignore the fire ball please --Server Script

local AimTesting = rs:FindFirstChild("AimTesting")
AimTesting.OnServerEvent:connect(function(p,Mouse)
    local bg = Instance.new("BodyGyro",Player.Character.HumanoidRootPart)
bg.D = 50
bg.MaxTorque = Vector3.new(math.huge,math.huge,math.huge)
for i = 1,50 do wait()
    bg.CFrame = CFrame.new(p.Character.HumanoidRootPart.Position,Mouse.hit.p)

--Local script

p = game.Players.LocalPlayer
Mouse = p:GetMouse()
m = game:GetService("UserInputService")
rs = game:GetService("ReplicatedStorage")
hb = game:GetService("RunService").RenderStepped
