Enhanced shadow orbs

[10leej]

So my shaodw orbs bar is giving me a nice little error

Interface\AddOns\oUF_Bob\embeds\oUF_ShadowOrbsBar.lua:29: 'for' limit must be a number

so I take a peak in my oUF_ShadowOrbsBar.lua\

on line 29 I have

for i = 1, PRIEST_BAR_NUM_ORBS do
  if i <= numOrbs then
    pb[i]:SetAlpha(1)
  else
    pb[i]:SetAlpha(.2)
  end
end

however there is a new perk that I discovered called Enhanced Shadow Orbs, now I have no idea what this actually is but apparently because of it I can't use PRIEST_BAR_NUM_ORBS to give me the maximum number of shadow orbs now

I'm wondering if this shows as a buff or not.

EDIT:
Actually scratch this entire thing I looked at what tukz was doing in tukui

local numOrbs = UnitPower("player", SPELL_POWER_SHADOW_ORBS)
local totalOrbs = IsSpellKnown(SHADOW_ORB_MINOR_TALENT_ID) and 5 or 3

for i = 1, totalOrbs do
	if i <= numOrbs then
		pb[i]:SetAlpha(1)
	else
		pb[i]:SetAlpha(.2)
	end
end

if(pb.PostUpdate) then
	return pb:PostUpdate(numOrbs)
end
