[SOLVED] Invalid argument #1 to 'pairs' (table expected, got Instance) ?

Hey guys need yall help with this i kept getting this error,

Also I'm using a module script, if you can help out i appreciate it.

local ZSModule = {}
function ZSModule.movezombieto(zom, pathtable, pos)
    local wal = zom:WaitForChild("Humanoid"):LoadAnimation(zom:WaitForChild("Config"):WaitForChild("WalkAnim"))
    wal.Priority = Enum.AnimationPriority.Action
    wal:Play()
    spawn(function() zombiehealthcheck(zom) end)

    spawn(function() 
        repeat wait(math.random(5,50)) 
            if zom:WaitForChild("Humanoid").Health > 0 then 
                zom:WaitForChild("Config"):WaitForChild("ZombieRawr"):Play()
                wait(math.random(4, 8))
                zom:WaitForChild("Config"):WaitForChild("ZombieRawr"):Stop()
            end 
        until zom:WaitForChild("Humanoid").Health > 0 
    end)
    for _, pathp in pairs(pathtable) do --Problem
        if zom:WaitForChild("Humanoid").Health > 0 then
            moveTo(zom:WaitForChild("Humanoid"), pathtable.Position)
            zom:WaitForChild("Humanoid").MoveToFinished:Wait()
        end
    end
end

return ZSModule

here's the script's parent or whatever you call it lol (summarised)

    for i = 1, zomcount, 1 do
