Inserting Rows and Columns in Microsoft Excel

When I add a rows and columns in excel some sort of error message appear. How can I resolve this problem and insert a rows and columns without facing the same problem?
Microsoft Excel
To prevent possible loss data, Microsoft Office Excel cannot shift nonblank cells off the worksheet.
Try to locate the last nonblank cell by pressing XTRL+END, and delete or clear all in cells between the last cell and the end of your date. Then select cell A1 and save your workbook to reset the last cell user.
Or, you can move to a new location and try again.
OK
