Cancel Save workflow that checks date field
                    Hello,
We need a workflow that will cancel a save anytime a sales rep indicates that we have to shop for an item and the customer requested date is less than 14 days.
 
 
 
                We need a workflow that will cancel a save anytime a sales rep indicates that we have to shop for an item and the customer requested date is less than 14 days.
So far I have 
written: 
(PRE('<bShopping_Cust_accepts_min_buy_requirements_ITAG>') = 
FieldValue('<bShopping_Cust_accepts_min_buy_requirements_ITAG>') OR 
PRE('<bShopping_Cust_accepts_min_buy_requirements_ITAG>') IS NULL) AND 
(FieldValue('<bShopping_Cust_accepts_min_buy_requirements_ITAG>')
This keeps the 
record from saving anytime someone checks the box - Shopping.  I need to 
incorporate the date field [<dDate_Proposal_due_to_customer_ITAG>] and get 
it to look to see if the date is less than 14 days....if the date is blank or 
less than 14 days I need the save to be canceled.
