Hello,
I am working on a project where I would like to have a customer
database in one workbook, and an invoice/PO generator in another
workbook. The PO generator will have either a drop down list or a
combo box which is linked to the customer database. The drop down
list would show all the customers and information about the customer
database.

I would like to use a drop down list on the PO sheet, so that a user
can scroll through all possible customers. But I have learned that a
drop down list can only be validated when the reference workbook is
open. And I would prefer that the customer database workbook remain
closed. So, first of all...can this be done with a drop down list?
If so, how? And...if it can't be done with a drop down list, what's
the next choice? I had assumed using a userform with a combo box
which contains a drop down list of customers.

Thanks in advance for your help.

Andy
