DE PROJECT STEPS 1. Alex Makula is a project manager for the Content Shop, an online firm based in New Haven, Connecticut, that provides written content for websites. Alex is compiling data on the contract writers and editors the company works with, and he asks for your help completing the workbook and analyzing the data. Switch to the Contract Writers worksheet, where Alex created a formula with the VLOOKUP function to look up contractor names by their contractor ID. Other project managers will use this workbook, and he wants to alert them when they enter an incorrect ID number. In cell B4, nest the existing VLOOKUP function in an IFERROR function. If the VLOOKUP function returns an error result, display "Invalid Contractor ID" as the error text. 2. Alex needs to complete the Writers table in the range A7:127. First, determine whether each contractor can write questions and answers for information websites. In cell G8, enter a formula using the IF function that uses a structured reference to the Years column ([@Years]) to determine if the value is greater than 1. The formula returns the text Yes if true and No if false. Fill the formula into the range G9:G27, if necessary. 3. Contractors who can write reviews must have at least 2 years of experience or an average evaluation rating from Contract Shop managers of 7 or more. In cell H8, enter a formula using the IF and OR functions to determine whether the value in the Years column is greater than or equal to 2 OR whether the value in the Avg Eval column is greater than or equal to 7 . Use a structured reference to both columns ([@Years] and [@[Avg EvaI]]). The formula returns the text Yes if a contractor meets one or both of the criteria, and it returns No if a contractor meets neither criteria. Fill the formula into the range H9:H27, if necessary. 4. Contractors can take copywriting assignments if they have at least 3 years of experience and a customer score of at least 7. In cell 18, enter a formula using the IF and AND functions to deterimine whether the value in the Years column is greater than or equal to 3 AND whether the value in the Avg Score column is greater than or equal to 7 . Use a structured reference to both columns ([@Years] and [@[Avg Score]]). The formula returns the text Yes if a contractor meets both criteria or the text No if a contractor meets none or only one of the criteria. Fill the formula into the range 19:127, if necessary, Content Shop Contract Writers Editing Groups - Platinum Level
