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)

iferror(VLOOKUP(Q2,CBFStaff[[Staff ID]:[Name]],2,FALSE), "Invalid Staff ID")

Explanation:

The vlookup formula is not given, but let me explain the general concept here,

iferror works typically like an if else statement, its syntax is IFERROR(value,value _ if _ error), if the it sequal to value, value is returned if not, the next argument is returned, so in this case, we will need to replace value with vlookup function and add an else argument like this

IFERROR(VLOOKUP(),"Invalid Staff ID")// now this will set the message if vlookup cannot find the value

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
