mmacro to copy last row to the next row

I have a calc sheet ino which I add daily measurements. I use a second sheet to enter my data as the first sheet is complex with additional columns with averages etc. I would like to run a macro which would find the last filled row and copy it to the row below. I have links in the new last row to my data entry sheet.

I am new to macros having recorded two. I have looked at the code and find it very difficult to understand.

Any help would be appreciated

A document with data and “exactly” you want, will help to who want help you.
