Shipping costs vary depending on method of shipping and the zone number of the destination. Creating a dynamic retrieval function leveraging the INDIRECT function can make it easily to calculate shipping costs for customers. On the Shipping Costs worksheet, create a Priority named range for cells A5:F10 and then create an Express named range for cells A15:F20. In cell 17, enter a VLOOKUP function to retrieve the correct shipping costs based on the weight and zone. Use the INDIRECT function for the table array, so that the customer can choose Express or Priority shipping. Change the shipping method from Priority to Express to ensure the correct shipping cost is retrieved.
