No, just that one line needs to be replaced with the 3 I put there.

If it then reports the same in combat error message on the lines underneath simply move the new end line down to beneath the block of 3 lines that show the tooltip.

So, first try it like this ..

if owner.aura and owner.active then
   if not InCombatLockdown() then
      self:SetID( owner.aura.id );
   end
   GameTooltip:SetOwner( owner );
   tooltipUpdate( owner );
   GameTooltip:Show();
   -- self:SetScript( "OnUpdate", tooltipUpdate );
end

And if it still errors out try it like this ...

if owner.aura and owner.active then
   if not InCombatLockdown() then
      self:SetID( owner.aura.id );
      GameTooltip:SetOwner( owner );
      tooltipUpdate( owner );
      GameTooltip:Show();
   end
   -- self:SetScript( "OnUpdate", tooltipUpdate );
end
