In Maintain Items on the Cost Break tab, I had a particular quantity to input for a specific amount for a vendor item. How do I enter a minimum quantity?

When I input the minimum quantity, I get an error message which says "Discount amount cannot be greater than Replacement Cost".

Price Break Quantity Example:

FROM RANGE                           TO RANGE                          AMOUNT

0                                             18,299                              $999.999

18300                                    50,000                             $0.37
