Allen,

I don't expect you to write things for me but I'm struggling with
understanding.  I'm using

'Purpose:   This module illustrates how to create a search form, _
           where the user can enter as many or few criteria as they
wish, _
           and results are shown one per line.
'Note:      Only records matching ALL of the criteria are returned.

as per your web site and dont understand how this then links in with

Function UnpickAll()
   Dim db As DAO.Database
   Dim strSql As String

   strSql = "UPDATE Table1 SET IsPicked = False WHERE IsPicked =
True;"
   Set db = DBEngine(0)(0)
   db.Execute strSql, dbFailOnError
   MsgBox db.RecordsAffected & " record(s) were unpicked."
   Set db = Nothing
End Function

I just don't know enough,  I think I'm getting confused because I'm
using a filter not a query?
