1. Dean wants a quick way to look up staff members by their Staff ID.

In cell Q3, nest the existing VLOOKUP function in an IFERROR function. If the VLOOKUP function returns an error result, the text Invalid Staff ID should be displayed by the formula. (Hint: You can test that this formula is working by changing the value in cell Q2 to 0, but remember to set the value of cell Q2 back to 1036 when the testing is complete.)

Current cell function is =VLOOKUP(Q2,CBFStaff[[Staff ID]:[Name]],2,FALSE)

2. In cell Q4, enter a formula using the VLOOKUP function to display a staff members years of service. Look up the staff ID listed in cell Q2. Use a structured reference to retrieve the value in the 4^th column of the CBFStaff table. Since the formula is looking for a specific staff members data, find an exact match.
