    • 120C: 4
  • We use the dollar sign symbols in front of the number to tell Excel to always reference that row in the equation, even though we will paste it for the entire column. Why is this important?
    • If you paste it through the entire column without the dollar sign, the box that you want for each equation won't normalize and it will be different for each equation. You need the dollar sign to keep the same box in each equation throughout the column.
  • Scan through your spreadsheet to find an example of the error message. Then go to the Edit menu and Select Replace. A window will open, type the text you are replacing in the "Find what:" field. In the "Replace with:" field, enter a single space character. Click on the button "Replace All" and record the number of replacements made in your wiki page.
    • No error messages.
