I am trying to make a dropdown box from a list of customers that are
contained in a database in a separate workbook. Is there a way I can use
Data Validation and have the source come from an entirely separate workbook?
Thanks

You can use a list from another open workbook, as described he

Yes you can, but generally the list will only work while you have the other
workbook open. Debra Dalgleish has some good information at
www.contextures.com on it: http://www.contextures.com/xlDataVal05.html

Probably a better, more 'robust' way that will work all the time is to set
up a worksheet that you will eventually hide from view. On that sheet, set
up an area with 1-to-1 links to the list in the other workbook. They don't
have to be in same cells, just have to have individual references. Example:
in the other workbook maybe your list is on Sheet1 and goes from A1:A10. You
could put a formula like this into B1 (or C99 or where ever)
=[SourceListBook.xls]Sheet1!$A1
and then fill it down to include all entries in the othe book. Now use this
copy of the list as your source for the Data Validation. The 1-to-1 links
will always update, even with the other workbook closed as long as your
system knows where that workbook is.
