In this project, you will complete a staff billing workbook similar to the one you worked on in Chapter 1. This worksheet is more complicated and uses a variety of formulas to calculate information about each staff member's weekly billing and to generate client bills from the staff hours. As you work on the Marshall Hours worksheet, you can use the Luz Hours or Stevens Hours worksheet as a guide. This is a long project. Be sure to save your work often!

1. Open the start file EX2013-SkillReview-3-1.The file will be renamed automatically to include your name. Change the project file name if directed to do so by your instructor, and save it.

2. If the workbook opens in Protected View, click the Enable Editing button in the Message Bar at the top of the workbook.

3. The Luz Hours and Stevens Hours worksheets are completed, but they contain errors. You'll need to fix
the errors before working on the Marshall Hours worksheet.

b. Click cell C4.
c. Notice the #NAME? error. Move your mouse over the Smart Tag icon to display a tool tip describing the possible error-The formula contains unrecognized text.
d. The formula =VLOOKUP(C3,BillableRates,4,FALSE) references the named range
BillableRates. That name has not yet been defined. That's what is causing the error.

4. Billable rates are kept in the Rates worksheet. Create the name BillableRates to use in formulas throughout the workbook.

18. There are errors in the Rate and Bill Amount columns. Use your error checking skills to track down the cause of the error.
a. On the Formulas tab, in the Formula Auditing group, click the Error Checking button to open the
Error Checking dialog.
b. After you've reviewed the first error, click the Next button to go to the next error. Continue reviewing each error and clicking Next until you receive the message that the error check is complete for the entire sheet. Click OK.

19. Did you notice that every error in the worksheet is a "value not available" error? You probably need
to dig deeper to find the root cause of the problem.
a. Click cell D6 and look at the formula in the formula bar: =B6*C6
b. Display the Trace Precedent and Trace Dependent arrows for this cell. On the Formulas tab, in the Formula Auditing group, click both the Trace Precedents button and the Trace Dependents button.
c. You can see that the problem appears to start in the precedent cell C6. Hide the arrows for cell D6 by clicking the Remove Arrows button, and then click cell C6 and click the Trace Precedents button.
d. Notice that one of the precedent arrows for cell C6 refers to another worksheet. Double-click the dashed precedent arrow line.
e. In the Go To dialog, click the worksheet reference and then click the OK button.

20. The link takes you to the Rates sheet where cells A2:D5 are selected. Notice that the
Name box displays the name ClientRates. (Depending on your screen resolution, the name may be slightly cut-off.) The formula in cell C6 is a lookup formula that uses the named range ClientRates as the Table_array argument. There are two problems with the definition
of the named range: It includes the label row (A2:D2), and it includes the employee number data (A2:A5).
a. On the Formulas tab, in the Defined Names group, click the Name Manager button.
b. Click the ClientRates name and review the cell range in the Refers to box. The range is incorrect. The ClientRates name should refer to cells B2:D5 on the Rates sheet.
c. Edit the range listed in the Refers to box to: =Rates!$B$2:$D$5
d. Click the Close button to close the Name Manager.
e. When Excel asks if you want to save the changes to the name reference, click Yes.

21. Now that the total bill amount is computing correctly, you can enter a formula in cell D14 to give the client the option of a monthly payment plan. You are authorized to offer a 6-month payment plan at a 2% annual percentage rate. Use cell references in the formula.
a. If necessary, click the Smith Bill sheet.
b. Click cell D14.
c. On the Formulas tab, in the Function Library group, click the Financial button.
d. Scroll down the list, and click PMT.
e. In the Function Arguments dialog, enter the Rate argument: D13/12
f. Click in the Nper argument box, and then click cell D12 (the number of payments).
g. Click in the Pv argument box, and then click cell D9 (the present value of the loan).
h. In the Function Arguments dialog, click OK. The completed formula should look like this: =PMT(D13/12,D12,D9)
i. The monthly payment amount appears as a negative number. That might be confusing to the client. Modify the formula so the result appears as a positive number.
j. Double-click cell D14 and type - between = and PMT.
k. Press Enter. The final formula should look like this: = -PMT(D13/12,D12,D9)

22. Save and close the workbook.

23. Upload and save your project file.
