I have a stock item that I have loaded that isn't stock on hand as yet as I haven't purchased the stock yet so no currency applicable yet , and cannot do a simply estimate to a customer as it gives me this error . I made the stock item inactive and redid new one and its still doing it. 

This same customer will allow any other item so there is no error on the customer page. The stock item creation doesn't ask for currency so cannot see how its drawing the conclusion that Im using 2 currencies
