Referring to external workbook in Data Validation

[aposatsk]

I have 2 workbooks. In one (1), i want to use Data Validation to creat
a drop down menu. The other (2) workbook has a range of data. In (1),
defined a range so that it uses the data in (2). I named it book4, an
it refers to: =[Book4.xls]Sheet1!$A$1:$B$4 . However, when i try t
enter "=book4" into Source in Data validation i get the error: You ma
not use references to other workbooks or worksheets in Data Validatio
Criteria".

But i clearly read that this is possible

I did this to fix the problem. Please tell me if this method is correc
and fool-proof.

Book 1 is where my validation is. Book 2 is where my data is. In boo
2, i highlighted the data and defined it as 'report'. In Book 1, i mad
another Name (Define) which goes to Book2 and gets 'report'; i name thi
"City". Then in data validation, i can enter City and it works
