How can I change the walkspeed of the players as a round is about to start?

I have added this code in several different locations throughout the script. Nothing is working. I really don't have any idea how to fix this, and I need help. Thank you. The attempt to change the walk speed is found at the top and bottom of the script.

character.WalkSpeed = 0

local plrs = {}

for i, player in pairs(game.Players:GetPlayers()) do
	if player then
		table.insert(plrs,player) --Add each player into the plrs table.
	end
end

-- Teleport players to the map

local SpawnPoints = ClonedMap:FindFirstChild("SpawnPoints")

if not SpawnPoints then
	print("Error: Spawnpoints not found!")
end

local AvailableSpawnPoints = SpawnPoints:GetChildren()

for i, player in pairs(plrs) do
	if player then
		character = player.Character
		
		if character then
			-- Teleport them
			
			character:FindFirstChild("HumanoidRootPart").CFrame = AvailableSpawnPoints[1].CFrame + Vector3.new(0,20,0)
			table.remove(AvailableSpawnPoints,1)
			
			
			
			--Give them their weapon.
			
			local equipped = game.ServerStorage.PlayerData[player.Name].Equipped
			
			if equipped.Value ~= "" then
				local weapon = game.ServerStorage.Items[equipped.Value]:Clone()
				weapon.Parent = player.Backpack
			else
				local Sword = ServerStorage.Sword:Clone()
				Sword.Parent = player.Backpack
			end
			
			local GameTag = Instance.new("BoolValue")
			GameTag.Name = "GameTag"
			GameTag.Parent = player.Character
			
		else
			--There is no character
			if not player then
				table.remove(plrs,i)
			end
		end
	end
end
