Why won't it teleport the zombies randomly?

Trying to make it teleport them all individually once to random coordinates to be spaced out and automated, but it won't teleport them at all. If I do this script without checking for the name it teleports them all to the same place. Why isn't it working?

local bool = game.ReplicatedStorage.value.roun -- boolvalue
local zombw = game.Workspace["coolboi"] -- unimportant
local drool = game.ReplicatedStorage.objects["Drooling Zombie"] -- mob
local zombie = game.ReplicatedStorage.value.zombie -- zombie amount
local rounds = game.ReplicatedStorage.value.roundn -- round number

bool.Changed:Connect(function(newval) -- checking if true
    if bool.Value == true then -- if value is true
        zombw:Destroy() -- unimportant
        rounds.Value = rounds.Value + 1 -- add value to round
        local potato = zombie.Value -- just localizing zombie value
        potato = rounds.Value *4 -- changing value to rounds x 4
        for i = 1,potato do  
            local drools = drool:Clone()-- cloning desired amount of zombies
            drools.Parent = game.Workspace -- zombies parent
                if drools.Name ~= ("Zombie")then  -- chcking the name
                        drools.PrimaryPart = drools:FindFirstChild("HumanoidRootPart") -- getting part
                    drools.PrimaryPart.Position = Vector3.new(math.random(-350,-156),.5,math.random(-236,-13)) drools.Name = ("Zombie") -- randomizing position within plate
                    drools.Name = ("Zombie") -- changing name
                        repeat until drools.Name == ("Zombie") -- making sure all have --same name and tele and to repeat
                    elseif drools.Name == ("Zombie") then print ("ZFound") end -- if they --do have the name print and end
                        end
                    end
            end)
