Sacred Shield Tag

[nin]

Hey guys!

Im using a tag for oUF that looks like this

spells["Sacred Shield"] = GetSpellInfo(148039)

oUF.Tags.Methods['SS'] = function(u) 
    local name, _,_,_,_,_, expirationTime, fromwho = UnitAura(u, spells["Sacred Shield"])
    if(fromwho == "player") then
        local spellTimer = (expirationTime-GetTime())
		local TimeLeft =  numberize(spellTimer)
        if spellTimer > 0 then
            return "|cffFFAB00"..TimeLeft.."|r"
        end
    end
end
oUF.Tags.Events['SS'] = "UNIT_AURA"

Can anyone help me understand or edit this so i can track the 30sec duration buff from sacred shield(looked through the ID's and pretty sure im using the right one). now i only get the 5 sec actual shield showing.

thanks!
