- Open the start file EX2019-FixIt-3-6. 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.
- If the workbook opens in Protected View, click the Enable Editing button in the Message Bar at the top of the workbook so you can modify the workbook.
- On the
*GuestList*sheet, check all the formulas. Cells to check are filled with the light purple color. Most of them need to be corrected. Use error checking as needed and/or display the formulas on-screen for easy viewing.- In the
*Name Tag*column, modify the formula to display the guest name in this format: BILL SMITH*Hint:*There are multiple errors in this formula. Fix the formula in cell D10 and then copy it to the other cells in the column. - Correct the function used in cell A3 to calculate the sum of the values in the
*NumAttending*column. - Correct the function used in cell A4 to count the number of values in the
*Street column.* - Correct the function used in cell A5 to count the number of blank cells in the
*NumAttending*column*.* - Correct the function used in cell A6 to display the largest value in the
*NumAttending*column*.* - Correct the function used in cell A7 to display the average value in the
*NumAttending*column*.*

- In the
- On the
*Shopping List*sheet, check all the formulas. Cells to check are filled with the light purple color. Most of them need to be corrected. Many of the problems on this worksheet can be solved by creating named ranges or using a name that already exists.- The formula in cell B2 uses the wrong function.
- The formulas in cells A9:A23 reference a named range that doesn’t exist. There is more than one correct way to fix this problem using the cell range A5:H18 on the
*Places to Shop*worksheet*.*You can create the named range referenced in the formulas, or you can change the function arguments to reference the cell range instead. - The formula in cell H9 results in the correct value. However, the workbook author copied this formula to the remaining cells in the column and those values are definitely not correct! Fix the formula in cell H9 and copy it to cells H10:H23.
*Hint*: Notice that cell H8 is named*Tax*.

- If you’ve fixed the formulas in cells H9:H23 correctly, the formulas in cells I9:I23 and G5 should calculate properly now. However, the formulas in cells G2:G4 still have errors that need to be fixed.
*Hint:*Use error checking as needed and/or display the formulas on-screen for easy viewing.- Correct the function used in cell G2 to average value of the
*Cost*column. - Correct the function used in cell G3 to display the largest value in the
*Cost*column. - Correct the function used in cell G4 to display the smallest value in the
*Cost*column.

- Correct the function used in cell G2 to average value of the
- On the
*Summary*sheet, you will be entering all the formulas. Cells to complete are filled with the light purple color.*Hint:*Use error checking as needed and/or display the formulas on-screen for easy viewing.- Cell B2 should use a function that will update the date to the current date every time the workbook is opened.
- Cell B4 references a named range that doesn’t exist. It should reference cell A4 on the
*Guest List*sheet. You can create the named range or edit the formula to reference the cell instead. - Cell B5 references a named range that doesn’t exist. It should reference cell A3 on the
*Guest List*sheet. You can create the named range or edit the formula to reference the cell instead. - Cell B8 is missing the formula to calculate whether or not the total
*Cost*with tax on the*Shopping List*sheet + the total*Cost*for purchasing and mailing invitations on the*Guest List*sheet is greater than the available cash. The cell should display*yes*or*no*. - Add a formula to cell B9 to calculate the amount to borrow (total
*Cost*with tax on the*Shopping List*sheet + the total*Cost*for purchasing and mailing invitations on the*Guest List*sheet – the cash available) if the value in cell B8 is*yes*. If the value in cell B8 is not*yes*, the cell should display 0. - Add a formula to cell B12 to calculate the monthly loan payment based on the information in cells B9:B11. Use a negative number for the
*Pv*argument*.*
