Luke wants a quick way to look up staff members by their employee id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text "invalid employee id" should be displayed by the formula. (hint: test if this formula is working by changing the value in cell q2 to 0, but remember to set the value of q2 back to 2005 when the testing is complete.)
