using ranges

[Guest]

I have a 3 column, around 400 rows of a spreadsheet. I named the list
customers and have it look like this:
=OFFSET(AR!$B$3,0,0,COUNTA(AR!$B:$B),COUNTA(AR!$1:$1))
When I try to use it I get an error message that says:"The list source
must be a delimited list, or a reference to a single row or column". I got
frustrated so I changed it so I could use only one column. However what can
I do to be able to use all three columns, or two columns?

Seems to work fine for me as long as you have data in row 1 to feed that
final argument. Can see rows changing, but probably not columns, so not
sure why you wouldn't just use 3 as opposed to COUNTA(AR!$1:$1) though
