12. Dean wants a quick wayr to look up staff members by their Staff ID. In cell Q3, nest the existing VLDDKUP function in an IFERRDR function. If the VLDUKUP function returns an error result, the text I"Iniuralid Staff ID"r should be displayed by the formula. {Hint You can test that this formula is working by changing the value in cell 02 to D, but remember to set the value of cell Q2 back to 1036 when the testing is complete.)
