Speed potion: Animation won't activate when clicking? How do I fix this?

I wanted to make this speed potion tool, I made an animation for it using animation editor. I'm new to scripting so I may have made a stupid mistake. Animations name is ZTZ, that's what that's about down there.

local CanActivate = true
local player = game.Players,LocalPlayer
local character = player.Character

script.Parent.Activated:connect(function()
    if CanActivate = true then
        local animation = character.Humanoid:LoadAnimation(script.Parent.ZTZ)
        animation:Play()
    end
end)

Any idea what I did wrong? Any help on this and how to avoid making the same mistake would be very helpful! Thank you! :D
