My hopperbin works when I test it, but not when in a server. How do I fix this? (solved)

I'm trying to create a hopperbin that has multiple uses. I've gotten this tool to work when I press play while in the Studio, but if I run a server and use the tool in there, one part of it will break. This part involves taking part from inside the hopperbin itself, cloning it and placing it in the workspace.

I'm a bit new to coding, so I'm having a hard time figuring out what the problem is here. If anyone could help me with this, I would be very grateful.

local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/Zanegsu-Slash-item?id=249793844"
local Tool = script.Parent
local Bullet = Tool:FindFirstChild("Part")
--Player
local plr = game.Players.LocalPlayer
--UserInputService
local uis = game:GetService('UserInputService')
local shooting = true

--Input Function
function Input(i)
    --Check key
    if i.KeyCode == Enum.KeyCode.F then
        if shooting == true then
            shooting = false
            animTrack = plr.Character.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid
            animTrack:Play()
            --Clone Rocket
            local Rocket = Bullet:Clone()
            --Parent clone
            Rocket.Parent = workspace
            --Position clone
            Rocket.Position = plr.Character.IchigoTorso.Shot.Position
            --Rotation clone
            Rocket.Rotation = plr.Character.Torso.Rotation
            wait(5)
            shooting = true
        end
    end
    if i.KeyCode == Enum.KeyCode.E then
        animTrack = plr.Character.Humanoid:LoadAnimation(animation) -- Load animation into Humanoid
        animTrack:Play()
    end
end

function onSelected()
    --Connect function
    uis.InputBegan:connect(Input)
end

script.Parent.Selected:connect(onSelected)

The line:

Rocket.Position = plr.Character.IchigoTorso.Shot.Position

Is referring to a model that I have attached to the player, which doesn't seem to be the problem with this script.
