Maximum Amount Allowed In Shopping Cart

This module allows you to set a Maximum Value for the Shopping Cart total. If the value is exceeded, the customer cannot proceed to checkout, but is alerted to Contact the Store Owner. (The text of this message can be editied to suit individual needs).
The module is useful for store owners who have a reason to set an upper limit on any single order value (eg: as is sometimes needed for credit card authorisation purposes, stock limitations, etc).
The value is set in the Maximum Values configurations in the Admin Panel, and can be any amount you choose. Leaving the value field empty renders the module inactive.
This module is a modification of the Minimum Value module by Andrew Berezin.
