Okey doke, you are using Super orders?

read this thread, as that error is related to

http://www.zen-cart.com/forum/showth...ate_diff%28%29

I think you may need to update super orders.

There is another thread where Kuroi or Vger mention that the name of this function was changed a while back to stop an error of somesort
Of course i can't find the thread right now
