Making an animation activate through chat?

Hello, I am working on making a dabbing script in my game and I want it to activate through "/e dab. It isn't working and I'm not sure why. It is located in Starter Player Scripts and it's a local script.

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://636749560"
local animtrack = nil
local canplay = true

function processCommand(speaker, message)
    if message == "/e dab" then
        if canplay then
            canplay = false
            local Cname = speaker.Name
            local character = game.Workspace.Cname
            animtrack = character.Humanoid:LoadAnimation(animation)
            animtrack:Play()
        end
    end
end

Any help is appreciated.
