Hi all,

I would like to use autofill in a macro, but the length of the range is
changing every time when I open the workbook.
The task would be that when I paste three column to range B:D, the macro
should autofill column A with numbers from 1 to the number of the last row.
For example, the last entry in column B is in row 67, autofill should fill
column A with numbers from 1 to 67.

Thank you in advance for!
