Help with displaying boss debuffs on raid frames

[maltese]

I'm trying to get certain debuffs to appear on my raid frames and I'm having some trouble figuring out how to filter them.

Layout code

	if self.raid then
		if whitelist.RaidDebuffs then
			-- raid debuffs testing----------------------------------------------------
			self.Debuffs = CreateFrame('Frame', nil, self)
			self.Debuffs.spacing = 1
			self.Debuffs.initialAnchor = 'TOPLEFT'
			self.Debuffs['growth-y'] = 'DOWN'
			self.Debuffs['growth-x'] = 'RIGHT'
			-- tiny icons
			self.Debuffs.numDebuffs	= 3
			self.Debuffs.size 		= 8
			self.Debuffs.spacing		= 1

			self.Debuffs:SetWidth(self.sizes.w)
			self.Debuffs:SetHeight(self.sizes.h)

			self.Debuffs:SetPoint('TOPLEFT', self.Health, 0, 0)
			self.Debuffs.CustomFilter	= ok.CustomAuraFilterRaid
		end

Whitelist module

local whitelist = {
RaidDebuffs = {
[GetSpellInfo(8921)] 	= { color = { 1, 0, 0 }},	--moonfire testing
	},
}

CustomAuraFilter code

function ok.CustomAuraFilterRaid(icons, unit, icon, name, rank, texture, count, dtype, duration, timeLeft, caster)
	if caster == 'player' then
		if	type(whitelist[ok.class][name]) == 'table' and
			whitelist[ok.class][name].colour
		then
			icon.colour = whitelist[ok.class][name].colour
			icon.maxc = whitelist[ok.class][name].maxc or nil
			return true
		end
	--end
	else -- added as a test to see if I can get debuff tracking on raid frames
		if	type(whitelist.RaidDebuffs[name]) == 'table' and
			whitelist.RaidDebuffs.colour
		then
			icon.colour = whitelist.RaidDebuffs.colour
			icon.maxc = whitelist.RaidDebuffs.maxc or nil
			return true
		end
	end
end

I'm obviously missing something, because debuffs are not appearing on my raid frames. If I take out the customaurafiltering I can get any debuff to appear on my raid frames.

Any ideas?

EDIT: I'm fairly certain I'm either doing the table wrong or calling the table wrong in the function. Any and all tips would be appreciated.

EDIT #2: I removed all the other sections in the whitelist, it would of been crazy long otherwise.
