why does the zombie spawner not spawn in the right place?

[ok i found solution]

script.Parent.Transparency = 1 

while wait(math.random(29, 90)) do -- random time to spawn
	z = game.ReplicatedStorage.zombie:Clone()
	local hp = z.Humanoid.MaxHealth
	z:MoveTo(script.Parent.Position) -- move to the spawner's location
	z.Parent = workspace
	z.Humanoid.MaxHealth = math.random(25,100) -- random health
	z.Humanoid.Health = z.Humanoid.MaxHealth
	if hp < 50 then --change skin collor due to health
		z["Left Arm"].Color = Color3.fromRGB(39, 70, 45)
		z["Right Arm"].Color = Color3.fromRGB(39, 70, 45)
		z["Head"].Color = Color3.fromRGB(39, 70, 45)
	else

		z["Left Arm"].Color = Color3.fromRGB(52, 142, 64)
		z["Right Arm"].Color = Color3.fromRGB(52, 142, 64)
		z["Head"].Color = Color3.fromRGB(52, 142, 64)

	end
end

it just ignores line 6 for some reason [ok i found solution]

2 Things I changed:

1. Put Waiting at the End and not inside while ... do so it always has a random time

2. SetPrimaryPartCFrame instead of MoveTo

script.Parent.Transparency = 1 

while true do -- random time to spawn

    z = game.ReplicatedStorage.zombie:Clone()
    local hp = z.Humanoid.MaxHealth
    z:SetPrimaryPartCFrame(script.Parent.Position) -- move to the spawner's location
    z.Parent = workspace
    z.Humanoid.MaxHealth = math.random(25,100) -- random health
    z.Humanoid.Health = z.Humanoid.MaxHealth
    if hp < 50 then --change skin collor due to health
        z["Left Arm"].Color = Color3.fromRGB(39, 70, 45)
        z["Right Arm"].Color = Color3.fromRGB(39, 70, 45)
        z["Head"].Color = Color3.fromRGB(39, 70, 45)
    else

        z["Left Arm"].Color = Color3.fromRGB(52, 142, 64)
        z["Right Arm"].Color = Color3.fromRGB(52, 142, 64)
        z["Head"].Color = Color3.fromRGB(52, 142, 64)

    end
wait(math.random(29, 90)) 
end
