My zombie wave loop script won't check if statement how to fix?

local val = game.ReplicatedStorage.numberval.Value


for i = 1,10 do
	game.ReplicatedStorage.bacteria:Clone()
	game.ReplicatedStorage.bacteria:Clone().Parent = workspace
	game.ReplicatedStorage.bacteria:Clone().HumanoidRootPart.Position = Vector3.new(math.random(-315.026, -268.827),-148.634, 2.76)
	print("spawned 1wave")
	wait()
end
while true do
if val == 10 then
	for i = 1,10 do
		game.ReplicatedStorage.bacteria:Clone()
		game.ReplicatedStorage.bacteria:Clone().Parent = workspace
		game.ReplicatedStorage.bacteria:Clone().HumanoidRootPart.Position = Vector3.new(math.random(-315.026, -268.827),-148.634, 2.76)
		print("spawned 2wave")
			wait()
			val = val + 1
	end
elseif val == 30 then
	for i = 1,10 do
		game.ReplicatedStorage.bacteria:Clone()
		game.ReplicatedStorage.bacteria:Clone().Parent = workspace
		game.ReplicatedStorage.bacteria:Clone().HumanoidRootPart.Position = Vector3.new(math.random(-315.026, -268.827),-148.634, 2.76)
		print("spawned 3wave")
		wait()
	end
elseif val == 40 then
	for i = 1,10 do
		game.ReplicatedStorage.bacteria:Clone()
		game.ReplicatedStorage.bacteria:Clone().Parent = workspace
		game.ReplicatedStorage.bacteria:Clone().HumanoidRootPart.Position = Vector3.new(math.random(-315.026, -268.827),-148.634, 2.76)
		print("spawned 4wave")
		wait()
	end
elseif val == 50 then
	for i,v in pairs(game.Workspace:GetChildren()) do
		if v.Name == "bacteria" and v.Humanoid then
			v:remove()
			print("removed waste.....")
		end
	end
	end
	wait(0.1)
end

Does not print anything but print("spawned wave1") Im trying to make "zombie" waves. Im not sure what the error is. No errors are shown in output And whenever a zombie is killed it adds 1 to the value, Ive checked the value succesfully changes to 10 after all the zombies are killed. So i dont know what to do
