Custom NPC + PathService Problem?

I wanted to make a custom NPCs, and they'll spawn in random locations, while moving to different locations as well. I've used a gear script and editted it to make it work as a normal script. I've made it work with pathways, but I think I'd rather have it wander around to random places.

while wait(5) do
local paths = script.Parent.Pathways:GetChildren()

    return table[math.random(#table)]
end

    local count = 0
    for _, child in pairs(Workspace:GetChildren()) do
        if child.Name == "Person" then
            count = count + 1
        end
    end
    return count

    for i = 1, 5 do
	number = math.random(1, (#paths))
        if getFans() <= 12 then
            local dummy = getDummy()
            dummy.NPC.WalkSpeed = math.random(11, 15)
            dummy.Target.Value = paths[math.random(1, (#paths))]
            dummy.Parent = Workspace
            dummy.Head:MakeJoints()
            wait()
            if math.random() > .2 then
                game:GetService("InsertService"):LoadAsset(getRandomValue(HATS)):GetChildren()[1].Parent = dummy
            end

            local torsoPosition = paths[number].Position

            local x = paths[number].Position.X
            local z = paths[number].Position.Z
            dummy:MoveTo(Vector3.new(math.random(x - 10, x + 10), paths[number].Position.Y, math.random(z - 10, z + 10)))
        end
    end
end

Here's the script in the dummy allowing it to walk, It may be helpful to solve the problem.

local function plusOrMinus(number)
	return math.random(number - 4, number + 4)	
end

local function randomize(v)
	return Vector3.new(plusOrMinus(v.X), plusOrMinus(v.Y), plusOrMinus(v.Z))
end

wait(math.random())
local walkspeed = script.Parent.NPC.WalkSpeed
local hum = script.Parent.NPC
local head = script.Parent.Head
local torso = script.Parent.Torso
local target = script.Parent.Target.Value
while true do
	if (torso.Position - target.Position).magnitude < 2 then
		hum.WalkSpeed = 0
	else
		hum.WalkSpeed = walkspeed
		hum:MoveTo(randomize(target.Position), target)
	end
	wait(1)
end
