Raidgroup # Display.

[sacrife]

Hi.
I've been trying to the raidgroup number of my raidgroups next to the raidframe, and I seem to have some problems creating the fontstrings.
Here's what I have so far.

if (GetNumRaidMembers() > 0) then
	local raidGroupYpos = -30
	local raidGroupXpos = 5
	local raidGroup1Text = CreateFontString(nil, "OVERLAY")
		raidGroup1Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos)
	local raidGroup2Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-10)
	local raidGroup3Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-20)
	local raidGroup4Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-30)
	local raidGroup5Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-40)
	local raidGroup6Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-50)
	local raidGroup7Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-60)
	local raidGroup8Text = CreateFontString(nil, "OVERLAY")
		raidGroup2Text:SetPoint("LEFT", UIParent, raidGroupXpos, raidGroupYpos-70)
	
	self:SetWidth(10)
	self:SetHeight(13)
	self:SetTextColor(1, 1, 1)
	self:SetFont("Interface\\AddOns\\!LynSettings\\fonts\\font2.ttf", 16, "OUTLINE")
	
	self:SetScript("OnUpdate", self.update)
	
    for i=1, MAX_RAID_MEMBERS do
		
        local _, _, subgroup, _, _, _, _, _, _ = GetRaidRosterInfo(i); --[[name, rank, subgroup, level, class, fileName, zone, online, isDead]]--
		
        if (subgroup == 1)then
			raidGroup1Text:SetText(subgroup)
		else
			raidGroup1Text:SetText("")
		end
		
		if (subgroup == 2) then
			raidGroup2Text:SetText(subgroup)
		else
			raidGroup2Text:SetText("")
        end

    end

end

Any ideas?
