    Double data validation list containing duplicate names to display unique names on dropdown

    Hi Guys,

    I am trying to make a workbook to make it easier when sending confirmations to my clients, I talk to many people during the day, and I always send an e-mail to both parties of what we talked about. I want to make it automated in order to save time, so here goes:

    I have a sheet called 'List' this is where the message will be, and data will be taken from other sheets, buyer and seller.
    Both Buyer and Seller sheets contains three columns: A is company name, B is Name and C is e-mail address.

    On the List sheet, I have four dropdown validation lists:
    1. Buyer Company name
    2. Buyer from company name
    3. Seller Company name
    4. Seller from company name

    I speak to many people from different companies, and I don't want to show repeated company names - so I made a new sheet where I place the pivot table for both buyer and seller, but I am stuck here, tried reading on OFFSET, but I just couldn't figure it out since I don't have much knowledge in VBA.

    I have attached a sheet to show more or less what I want.

    I appreciate it if anyone can help me :D

    Re: Double data validation list containing duplicate names to display unique names on drop

    You have the right idea to make unique lists by using a pivot table. Now what you need to do is overlay a named dynamic range over them.

    See this wiki for information on the offset command and named dynamic ranges: http://www.utteraccess.com/wiki/inde...Dynamic_Ranges

    I changed your two ranges to:
    t_buyers =OFFSET(Tables!$A$5,0,0,COUNTA(Tables!$A:$A)-3,1)
    t_seller =OFFSET(Tables!$D$5,0,0,COUNTA(Tables!$D:$D)-3,1)

    Re: Double data validation list containing duplicate names to display unique names on drop

    Thanks dflak, it worked!

    I just have two other problems now, the list will be eventually growing with new companies and staff.
    I added a new company for a test, and it did not show on the list.
    1. I need it to organically grow together with the list.
    2. I need a dropbdown list with the contact of the company

    Is it possible to do it?

    Edit: I got the organic growth... I must be tired... I had to refresh the Pivot table, and changed the code to =OFFSET(Pivot!$A$5,0,0,COUNTA(Pivot!$A:$A)-2,1) // -2 instead of -3

    Add the buyers and sellers to the Excel tables on the Buyer and Seller tabs. Then refresh the pivot tables on the tables tab. The named ranges should adjust automatically.

    This article explains named ranges and the offset command: http://www.utteraccess.com/wiki/inde...Dynamic_Ranges

    The named ranges were adjusted, thanks, it is now following the formula - I had just forgotten to refresh (eyes are tired)

    Did do some reading there and understood a bit more now on offset and named ranges, nice to understand how it works and how the COUNTA can be used there

    Now on the name of the person I was in touch with, having in mind that one company can have more than one contact (reason why I wanted to slim it down with pivot table), how can I choose the contact?

    For instance, I pick company Wolthers Douqué and the person I was in touch with was Joe, but there are three other choices. Can I do as follows?

    Tried editing but it would just delete my post above.

    Tried something like this now after doing a bit more research, but still getting errors.

    Re: Double data validation list containing duplicate names to display unique names on drop

    Now you are talking about cascaded dropdown lists. I have a wiki (or 2) for that as well. Take a look them and if you have questions, give a shout:

    There are two ways of doing it:

    Non-VBA: http://www.utteraccess.com/wiki/inde..._%28Non-VBA%29

    and VBA: http://www.utteraccess.com/wiki/inde...ists_%28VBA%29

    I think you are well set up to use the Non-VBA method.
