        end
end
 
for i=1,4 do
        local f = _G["PartyMemberFrame"..i]
        f:UnregisterEvent("UNIT_AURA")
        local g = CreateFrame("Frame")
        g:RegisterEvent("UNIT_AURA")
        g:SetScript("OnEvent",function(self,event,a1)
                if a1 == f.unit then
                        RefreshBuffs(f,a1,20,nil,1)
                end
        end)
        for j=1,20 do
                local l = f:GetName().."Buff"
                local n = l..j
                local c = CreateFrame("Frame",n,f,"TargetBuffFrameTemplate")
                c:EnableMouse(false)
                if j == 1 then
                        c:SetPoint("TOPLEFT",48,-32)
                else
                        c:SetPoint("LEFT",_G[l..(j-1)],"RIGHT",1,0)
                end
        end
end

So I found this... and it does pretty much what I want it to do, but I want this to be on the ArenaEnemyFrames... I can't figure out how to get it to show for those, I figured changing it to this would work:

for i=1,4 do
 local f = _G["ArenaEnemyFrame"..i]
 f:UnregisterEvent("UNIT_AURA")
 local g = CreateFrame("Frame")
 g:RegisterEvent("UNIT_AURA")
 g:SetScript("OnEvent",function(self,event,a1)
 if a1 == f.unit then
 RefreshDebuffs(f,a1,20,nil,1)
 else
 if a1 == f.unit.."pet" then
 PartyMemberFrame_RefreshPetDebuffs(f)
 end
 end
 end)
 local b = _G[f:GetName().."Debuff1"]
 b:ClearAllPoints()
 b:SetPoint("LEFT",f,"RIGHT",-7,5)
 for j=5,20 do
 local l = f:GetName().."Debuff"
 local n = l..j
 local c = CreateFrame("Frame",n,f,"PartyDebuffFrameTemplate")
 c:SetPoint("LEFT",_G[l..(j-1)],"RIGHT")
 end
end
 
for i=1,4 do
 local f = _G["ArenaEnemyFrame"..i]
 f:UnregisterEvent("UNIT_AURA")
 local g = CreateFrame("Frame")
 g:RegisterEvent("UNIT_AURA")
 g:SetScript("OnEvent",function(self,event,a1)
 if a1 == f.unit then
 RefreshBuffs(f,a1,20,nil,1)
 end
 end)
 for j=1,20 do
 local l = f:GetName().."Buff"
 local n = l..j
 local c = CreateFrame("Frame",n,f,"TargetBuffFrameTemplate")
 c:EnableMouse(false)
 if j == 1 then
 c:SetPoint("TOPLEFT",48,-32)
 else
 c:SetPoint("LEFT",_G[l..(j-1)],"RIGHT",1,0)
 end
 end
end

But... I just get a lua error that the value for 'b' is nil.

What I don't understand is, if it's using the PartyDebuffFrameTemplate to size the buffs etc... why can't it just attach that to the ArenaEnemyFrame and update when a new AURA happens?

And from my understanding it's pulling the value for B off of

local f = _G["ArenaEnemyFrame"..i]

...So why would it cause it to be nil?
