how do i fix this? i tried to make a skill that can get reward [closed]

    script.Parent.OnServerEvent:Connect(function(plr)
    wait(0.3)
    local Slash = game.ReplicatedStorage.cutslash:Clone()
    Slash.Parent = workspace
    Slash.CanCollide = false
    Slash.Anchored = true
    Slash.CFrame = plr.Character.HumanoidRootPart.CFrame * CFrame.new(0,0,-5) * CFrame.fromEulerAnglesXYZ(0,110,0)
    Slash.Touched:Connect(function(hit, plr)
        if hit.Parent:FindFirstChild("Humanoid") and hit.Parent.Name ~= plr.Name then
            local Ball = game.ReplicatedStorage.redball:Clone()
            local tag = Instance.new('ObjectValue',hit.Parent.Humanoid)
            tag.Name = 'creator'
            tag.Value = [help]
            Ball.Parent = workspace
            Ball.CFrame = Slash.CFrame

            Ball.Anchored = true
            Slash:Destroy()
            hit.Parent.Humanoid:TakeDamage(25)  
            for i = 1,18 do
                wait(.05)
                Ball.Size = Ball.Size + Vector3.new(0.3,0.3,0.3)

            end 
            wait(2)
