Why doesn't my script change anything?

I made an ability chooser, and when you choose something, it changes a numbervalue to a certain number, which it does, and the script is supposed to change what happens when you press Q because of this value, but it doesn't change at all. Help would be nice.

local pow = game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("PowerGui2"):WaitForChild("Frame")
local ability = pow.Power.Value

local plr = game.Players.LocalPlayer.Character
local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(inputObject, gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.Q and ability == 1 then
            game.ReplicatedStorage.Speedparticle:Clone().Parent = game.Players.LocalPlayer.Character:FindFirstChild("UpperTorso")
            game.Players.LocalPlayer.Character:FindFirstChild("Humanoid").WalkSpeed = 40
            wait(10)
                game.Players.LocalPlayer.Character:FindFirstChild("UpperTorso").Speedparticle:Remove()
            game.Players.LocalPlayer.Character:FindFirstChild("Humanoid").WalkSpeed = 16
        end

local RS = game:GetService("ReplicatedStorage")

local remoteEvent = RS:WaitForChild("RemoteEvent")

UIS.InputBegan:Connect(function(inputObject, gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.Q and ability ==2 then
        remoteEvent:FireServer() --Nothing passed to the server
						wait(0.5)
		for i, Child in pairs(plr:getChildren()) do
			if Child:IsA('Part') or Child:IsA('MeshPart') or Child:IsA('Accessory') then
				Child.Transparency = 0.5
			end
		end	
		plr:FindFirstChild("Head").face.Transparency = 0.5
		plr:FindFirstChild("HumanoidRootPart").Transparency = 1
		wait(9.5)
		for i, Child in pairs(plr:getChildren()) do
			if Child:IsA('Part') or Child:IsA('MeshPart') or Child:IsA('Accessory') then
				Child.Transparency = 0
			end
		end	
			plr:FindFirstChild("Head").face.Transparency = 0
		plr:FindFirstChild("HumanoidRootPart").Transparency = 1
    end
end)
