Why wont these animations play?

I have a script that should be cycling through a table of strings, and playing an animation based on which string is in the value at the time. Upon closer inspection, I found that the second value (DodgeAsset) Was not being changed for some reason. Any help is appreciated!

local C = script.Parent.Humanoid


Left = ("http://www.roblox.com/Asset?ID=318876532")
Right = ("http://www.roblox.com/Asset?ID=318875300")
CenterOverhead = ("http://www.roblox.com/Asset?ID=326759151")
LeftDodge = ("rbxassetid://326770084")
RightDodge = ("rbxassetid://326769779")

function ChooseAttack()
local AttackList = {"Left","Right","CenterOverhead"}
local A = script.Parent.DummyBrains.CombatValues.Asset
while wait() do
A.Value = AttackList[math.random(1, #AttackList)]       
end
end

function ReactAndDodge()
local DodgeList = {"LeftDodge","RightDodge"}
local A = script.Parent.DummyBrains.CombatValues.DodgeAsset
while wait() do
A.Value = DodgeList[math.random(1, #DodgeList)]     
end
end


function PlayAttack()
        local A = Instance.new("Animation")
        A.AnimationId = (script.Parent.DummyBrains.CombatValues.Asset.Value)
        local animTrack = C:LoadAnimation(A)
        animTrack:Play()
end

function PlayDodge()
    local A = Instance.new("Animation")
        A.AnimationId = (script.Parent.DummyBrains.CombatValues.DodgeAsset.Value)
        local animTrack = C:LoadAnimation(A)
        animTrack:Play()
end

while wait() do     
    ChooseAttack()
    PlayAttack()
    wait(0.5)
    ReactAndDodge()
    PlayDodge()
end
