Why is "GetMarkerReachedSignal" not firing?

it seems that the print statement I placed won't run, even though I went to moon animator and inserted a marker with the name "STARTMOVE". any solutions?

local loadm1 = hum:LoadAnimation(m1)

game:GetService("UserInputService").InputBegan:Connect(function(input, gp)
    if input.KeyCode == Enum.KeyCode.E and gp == false then
        hum.WalkSpeed = 0
        loadm1:Play(0)
        hrp.m1:Play()

        local con 
        con = loadm1:GetMarkerReachedSignal("STARTMOVE"):Connect(function() 
            print("thingy")
        end) 

        loadm1.Stopped:Wait()
        hum.WalkSpeed = 12
    end
end)
