Is this more along the lines of what needs to be done?

local function Update(self, t)
            if playerRole == nil then
                Text:SetText(hexa.."No Stats"..hexb)
            else
                if playerRole == GetSpecializationRole("TANK") then 
                    UpdateTank(self)
                elseif playerRole == GetSpecializationRole("HEALER") then
                    UpdateCaster(self)
                elseif playerRole == GetSpecializationRole("DAMAGER") then
                    UpdateDamager(self)
                end
            end
        end
