Help with checking a Players Role

[cokedrivers]

So im trying to get the players role with the following code:

local isCaster = {
	-- All Classes are needed as to not cause a error when the table is called.
	-- SpecID - Spec - Role
	DEATHKNIGHT = {
		nil, -- 250 - Blood - (TANK) 
		nil, -- 251 - Frost - (MELEE_DPS)
		nil, -- 252 - Unholy - (MELEE_DPS)
	},
	DEMONHUNTER = {
		nil, -- 577 - Havoc - (TANK)
		nil, -- 581 - Vengeance - (MELEE_DPS)
	},
	DRUID = { 
		true, -- 102 - Balance - (CASTER_DPS)
		nil,  -- 103 - Feral - (MELEE_DPS)
		nil,  -- 104 Guardian - (TANK)
		nil,  -- 105 Restoration - (HEALER)
	},
	HUNTER = {
		nil, -- 253 - Beast Mastery - (RANGED_DPS)
		nil, -- 254 - Marksmanship - (RANGED_DPS)
		nil, -- 255 - Survival - (RANGED_DPS)
	},
	MAGE = { 
		true, -- 62 - Arcane - (CASTER_DPS)
		true, -- 63 - Fire - (CASTER_DPS)
		true, -- 64 - Frost - (CASTER_DPS)
	}, 
	MONK = {
		nil, -- 268 - Brewmaster - (TANK)
		nil, -- 269 - Windwalker - (MELEE_DPS)
		nil, -- 270 - Mistweaver - (HEALER)
	}, 
	PALADIN = {
		nil, -- 65 - Holy - (HEALER)
		nil, -- 66 - Protection - (TANK)
		nil, -- 70 - Retribution - (MELEE_DPS)
	},
	PRIEST = { 
		nil,  -- 256 - Discipline - (HEALER}
		nil,  -- 257 - Holy - (HEALER)
		true, -- 258 - Shadow - (CASTER_DPS)
	},
	ROGUE = {
		nil, -- 259 - Assassination - (MELEE_DPS)
		nil, -- 260 - Combat - (MELEE_DPS)
		nil, -- 261 - Subtlety - (MELEE_DPS)
	}, 
	SHAMAN = { 
		true, -- 262 - Elemental - (CASTER_DPS)
		nil,  -- 263 - Enhancement - (MELEE_DPS)
		nil,  -- 264 - Restoration - (HEALER)
	},
	WARLOCK = { 
		true, -- 265 - Affliction - (CASTER_DPS)
		true, -- 266 - Demonology - (CASTER_DPS)
		true, -- 267 - Destruction - (CASTER_DPS)
	}, 
	WARRIOR = {
		nil, -- 71 - Arms - (MELEE_DPS)
		nil, -- 72 - Furry - (MELEE_DPS)
		nil, -- 73 - Protection - (TANK)
	},
}


local spec = GetSpecialization()
if not spec then
	playerRole = nil
	return
end

local specRole = GetSpecializationRole(spec)
if specRole == "DAMAGER" then
	if isCaster[class][spec] then
		playerRole = "CASTER"
		return
	end
end

local playerRole = specRole

but it is not pulling any info when i us it in one of my stats like:

	local function Update(self, t)
		
		int = int - t
		if int > 0 then return end
		active = GetActiveSpecGroup(false, false)
		if playerRole~= nil then
			Text:SetFormattedText(talentString, hexa..select(2, GetSpecializationInfo(GetSpecialization(false, false, active)))..hexb)
		else
			Text:SetText(hexa.."No Spec"..hexb)
		end
		int = 2

		-- disable script	
		--self:SetScript('OnUpdate', nil)
		
	end

can anyone help out with this.

Now i do get it to wrok if i use Ace3 Libs but Im trying to get my addon as slim as possible.

Thanks in Advance
