Another Error in shopping cart

[eluser]Unknown[/eluser]
I believe it means that $this->MOrders is null, hence you are trying to call a function on a non-object. It's probably not loading correctly. Can you list two things?

1) The line that loads the model in the controller
2) The name of the file that contains the model

I have run into this before when the filename containing the model started with an upper case character.

-pc
