Animate other players with Animation GUI?

I am trying to animate specific players in my game with an animation GUI. I want to be able to control other players' animations with only my GUI. When I click the animation button on the GUI it doesn't play, but when they click it, it plays. I think it has something to do with the local parts of the script but I'm unsure..

wait(1)
local frame=script.Parent
local user=game.Players.xoisi -- player name
repeat wait() until user.Character local char=user.Character
local humanoid=char:WaitForChild("Humanoid")
local anim
function playanim(id)
    if char~=nil and humanoid~=nil then
        local id="rbxassetid://"..tostring(id)
        local oldanim=char:FindFirstChild("LocalAnimation")
        if anim~=nil then
            anim:Stop()
        end
        if oldanim~=nil then
            if oldanim.AnimationId==id then
                oldanim:Destroy()
                return
            end
            oldanim:Destroy()

        end
        local animation=Instance.new("Animation",char)
        animation.Name="LocalAnimation"
        animation.AnimationId=id
        anim=humanoid:LoadAnimation(animation)
        anim:Play()
    end
end
local b1=frame.HighNote
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.HighNoteII
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Singing
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.SingingLoop
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Dance
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Dance2
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Dance3
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Wave
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Cheer
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.WalkSing
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.BabyIDanceBreak
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.BabyIDanceBreakII
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)
local b1=frame.Crouch
b1.MouseButton1Down:connect(function() playanim(b1.AnimID.Value) end)

This is the script I'm using
