WoWInterface - moving partymember debuffs

Hey,
I hope you guys can help me...

I'd like to adjust the partymemberframe debuffs, but i'm really bad at lua etc ;)
I tryed something like:

Lua Code:

PartyMemberFrame1Debuff1:ClearAllPoints()
PartyMemberFrame1Debuff1:SetPoint("BOTTOMLEFT",PartyMemberFrame1,"BOTTOMLEFT", 45, -4) 
PartyMemberFrame1Debuff1.SetPoint=function()end

and

Lua Code:

for i = 1, MAX_PARTY_MEMBERS do
    local f = _G["PartyMemberFrame"..i.."Debuff1"]
    f:SetPoint("BOTTOMLEFT", _G["PartyMemberFrame"..i], "BOTTOMLEFT", 45, -4)
end

without any success.

TY!
