Filtering Enabled + Animation? Need help!

I know how to script but not with remoteevents and stuff in mind. The animations and script will work in studio but not server/game

Here is how the tool is laid out:

Tool
    -Script
            -Local Script
    -Handle
    -Musket(Folder)
             -aniEvent
             -Animations
                      -Idle
                       -Reload
                        -Rest

Here is what is in the script

--------------------------------------------------

local aniEvent = script.Parent.Musket.aniEvent

--------------------------------------------------

local onKey = function(input)
    if input.KeyCode == Enum.KeyCode.R then
        return "Reload"
    elseif input.KeyCode == Enum.KeyCode.F then
        return "Rest"
    elseif input.KeyCode == Enum.KeyCode.C then
        return "Idle"
    end
end

script.Parent.Equipped:connect(function()

    for i,v in pairs(script:GetChildren())do
        v.Disabled = false
    end

    local player = game.Players:GetPlayerFromCharacter(script.Parent.Parent)

    aniEvent:FireClient(player,script.Parent.Parent.Musket.Animations.Idle)

    game:service("UserInputService").InputBegan:connect(function(input)

        local action = onKey(input)

        if action ~= nil then
            aniEvent:FireClient(player,script.Parent.Parent.Musket.Animations:findFirstChild(action))
        end

    end)

end)

Here is local

--------------------------------------------------

local aniEvent = script.Parent.Parent.Musket.aniEvent

aniEvent.OnClientEvent:connect(function(animation)
    local track = game.Players.LocalPlayer.Character:findFirstChild("Humanoid"):LoadAnimation(animation)
    track:Play()
end)

--------------------------------------------------

My objective is to atleast to get animations running in game.>
