attempt to index local "ball". Even though the ball is in the character?

What im trying to do is making the basketball shoot or in other terms making the part go to where the person is looking at when he clicks down. Keep in mind the basketball is a part and not a tool.

local function Shoot_Event()
	local ball = Character:WaitForChild("Ball")
	if ball then
	local Hit = Mouse.Hit.p
	local ShootingPosition = Character.PrimaryPart.Position
	local HeadLook = (Hit - Character.Head.Position).unit
	local SpawnPosition = ShootingPosition + HeadLook * 5
	local Power = ball.Power.Value
	print("work")
	ShootingEvent:FireServer(Hit, SpawnPosition, Power)
	end 
end

this local script works fine

local function Server_Shoot(Player, Hit, SpawnPos, Power)
	local Character = Player.Character or game.Workspace:FindFirstChild(Player.Name)
	local ball = Character:FindFirstChild("Ball")
		ball.Parent = game.Workspace
		ball.Position = SpawnPos
		ball.LastPlayer.Value = Player
		ball.Velocity = (Player.Character.Head.Position - Hit).unit * - Power + Vector3.new(0,50,0)
	end

But however this server script doesn't for some reason it says "attempt to index local "ball" (a nil value)

Based on the differences between the local and server scripts, the ball probably doesn't exist quite yet when it's being looked for in the server script. The LocalScript uses WaitForChild() while the Script uses FindFirstChild(). Try switching FindFirstChild() to WaitForChild() in the server script and see if that helps.
