Excel error msg when inserting new column

[ARV]

I got following error msg when inserting a new column. Does anyone
know what the msg is about?

"To prevent possible loss of data, microsoft excel can not shift
nonblank cells of the worksheet. Try to delete or clear the cells to
the right and below your data. Then select cell A1, and save your
workbook, to reset the last cell used. Or you can move the data to a
new location and try again"

Hi
you somehow have set the used range to the last column.
You may try the instructions on the following site:

to clear the used range. After this inserting columns
should work again
