I have a defined NAME(e.g. GROUP1) of a group of Cells in a table. Within
this group of cells, I had defined another NAME (e.g. GROUP_1) for those
blank cells that I gathered. My problem is how to make dynamic changes on
the referred cells of GROUP_1, say if I place value in one blank cell, the
GROUP_1 will be updated.

GROUP1 : A1:J5
GROUP_1 : A2,J4 <BLANK CELLS

Editing the GROUP1, I delete the content of B1 and B2...
Hence, I need GROUP_1 to recognize the changes
GROUP_1 must be : A2,J4,B1,B2

I hope this is not another unsolved problem in our forum....

thanks a lot...
