Hi Harry

Just right click on the Design table -> Properties
You will the File Path and next to it a Button with 3 dots -> click on it 

Browse to your Excel file and you relink it.

Hi, Rami,

      I tried. It doesn't work. I tried to linked to a  excel file of previous revision . That doesn't work either.  ---Harry
