4) Attendees who are also board members receive a discount off the registration fees. The discount amount varies based on the type of event. In cell J11, enter a formula that will return the discount amount if the registrant is a board member and return a blank value ("") if they are not. Use a XLOOKUP function, with the value retrieved by a VLOOKUP using the EventDetails named range as the lookup_value, the range B5:B8 as the lookup_array, and the range A5:A8 as the return_array. Use an IF function so that the discount only applies to board members. Format the result as Percentage with 0 decimal places. Copy the formula down through J30. 15

5) First Resource is offering a 5% discount off registration fees for all EventTypes except for Survey/Study. In cell K11, enter a formula that will return 0.05 if the event is NOT a Survey/Study, otherwise return a blank value (""). Use a VLOOKUP function to return the EventType from the EventDetails named range. Use a NOT function so that any event type other than Survey/Study will return TRUE. Use an IF function to return 0.05 for the value_if_true and "" for the value_if_false. Incorporate an IFERROR function to return a blank value if the VLOOKUP function returns an error. Format the result as Percentage with 0 decimal places and copy the formula down through K30. 12
