See attached file. We want to be able to have clients sign in from our company's website with a user name and password. The login needs to be validated and then will pass the visitor over to a predetermined order page designed for him to place an order. The items will be provided in a Google docs spreadsheet to create the items in the cart Items are added to the cart and then paid for at Google checkout. So the order page needs to only be accessible with that user name and password. See attached file showing how it should work.
No novices at this project please . You will need to show your knowledge of using these tools.
