Why can't players see my animation?

I'm making a running animation script but other players can't see my animation other than me

Here's my localscript

local p = game.Players.LocalPlayer 
local char = p.Character 
if not p.Character then 
    repeat wait() until p.Character 
end

local human = char.Humanoid 
local anim = game.Workspace:WaitForChild("Animation")
local loadAnim = human:LoadAnimation(anim) 


local UIS = game:GetService("UserInputService")

local holdingShiftKey = false


UIS.InputBegan:Connect(function(inputObject) 

    if(inputObject.KeyCode==Enum.KeyCode.E)then
       holdingShiftKey = true


        if holdingShiftKey then
            loadAnim:Play()

           repeat wait(.5)
    char.Humanoid.WalkSpeed += 1
        until char.Humanoid.WalkSpeed == 25 or not holdingShiftKey 

        end

    end
end)


UIS.InputEnded:Connect(function(inputObject)

    if(inputObject.KeyCode==Enum.KeyCode.E)then
                holdingShiftKey = false
        char.Humanoid.WalkSpeed = 16
        loadAnim:Stop()
    end
end)

Can anyone help me with this?
