Hi -
I have three tables with the column Updated_Date

Company.Updated_Date
Contacts.Updated_Date
Activity.Updated_Date

What I would like to happen is:
If the Updated_Date in any of the above tables is greater than 1/1/2009,
then I would like the Companies to show in my ListBox (Control Name: List16)

My form name is CompanyMain

Currently the rowsource for List16 is:
    Me.List16.RowSource = "SELECT Company.Company_Name, Company.DUNS_Number FROM Company GROUP BY Company_Name, DUNS_Number;"

Note: Company.DUNS_Number is Unique and shown in all tables.

If the Box is UnChecked the ListBox would revert to it's orig list.
Or I have a Reset Command Button I could add a line to to clear the criteria...
Thanks for your help.
Stacy

Are you saying that these 3 tables are related by the DUNS_Number field?
And are you just needing help with the construction of the SELECT statement, or do you need help with more than that?

I'll see if I can post an answer tomorrow evening if someone else doesn't get to it first.

To get the rowsource for your listbox you will have to find all the DUNS numbers from all the tables that have an updated date >1/1/2009.

You do this in a Union query.

Select Duns_Number from Company where Updated_Date >=#2009/01/01#
Union
Select Duns_Number from Contacts where Updated_Date >=#2009/01/01#
Union
Select Duns_Number from Activity where Updated_Date >=#2009/01/01#

Save this as qry1

Change the rowsource to:
"SELECT Company.Company_Name, Company.DUNS_Number FROM Company
Inner Join qry1 on company.DUNS_Number = qry1.DUNS_Number
 GROUP BY Company_Name, Company.DUNS_Number;"
