How would I stop an anim if the player sits down? [Solved]

Hey there I know that this may seem simple to a lot of you but for some reason despite being an average coder i can't do this right now.

I have this animation played on click but i don't know how to stop the anim if the player sits down I tried a few things like while loops and if statements i just don't know what to do please help :) Btw the script and anim are children of a button gui.

local player = game.Players.LocalPlayer
local character = player.Character
repeat wait()
    character = player.Character
until character
local hum = character:WaitForChild("Humanoid")
local emote = hum:LoadAnimation(script.Parent.Emote)
playing = false


script.Parent.MouseButton1Click:connect(function()
    if playing == false then
      if game.Players.LocalPlayer.Character.Humanoid.Sit == false then
        emote:Play()
        hum.WalkSpeed = 9
        hum.JumpPower = 0
        playing = true
      end
    elseif playing == true then
        emote:Stop()
        hum.WalkSpeed = 16
        hum.JumpPower = 50
        playing = false
    end
end)
