Search button in Master-Detail form

Hello there. Here is the problem. I have made a Search button to locate records in a DB. It works fine in my 'Simple Form' project but I cannot do the same for the 'Master Detail Form'project (As you may recognize it is a VB6 wizard generated Form). Please help me!


**************Simple Form********************

Dim dbVideo As Database
Dim rsCustomers As Recordset

Private Sub Form_Load()
Set dbVideo = OpenDatabase("c:\Orders.mdb")
SQLQuery = "SELECT * FROM Customers"
Set rsCustomers = dbOrders.OpenRecordset(SQLQuery)
txtFields(0) = rsCustomers.Fields("CustID")
txtFields(1) = rsCustomers.Fields("Name")
txtFields(2)= rsCustomers.Fields("Phone")
End Sub


Private Sub CustomerSearch_Click()
SQLQuery = "SELECT * FROM Customers WHERE Name LIKE '*" & txtFields(1) & "*'"
Set rsCustomers = dbVideo.OpenRecordset(SQLQuery)
txtFields(0) = rsCustomers.Fields("CustID")
txtFields(1) = rsCustomers.Fields("Name")
txtFields(2)= rsCustomers.Fields("Phone")
End Sub



**************Master-Detail Form********************

Dim rsCustomers As Recordset

Private Sub Form_Load()
Dim db As Connection
  Set db = New Connection
  db.Open "Provider = MSDataShape;Data PROVIDER = Microsoft.Jet.OLEDB.4.0;Data

Source=C:\Orders.mdb;"
 
  Set rsCustomers = New Recordset
  rsCustomers.Open "SHAPE {select CustID,Name,Phone from Customers} AS ParentCMD APPEND

({select CustID,ProdID,Quantity,Total from Orders } AS ChildCMD RELATE CustID TO CustID) AS ChildCMD", db, adOpenStatic, adLockOptimistic
 
  Dim oText As TextBox
  'Bind the text boxes to the data provider
  For Each oText In Me.txtFields
    Set oText.DataSource = rsCustomers
  Next
  Set grdDataGrid.DataSource = rsCustomers("ChildCMD").UnderlyingValue
  mbDataChanged = False
End Sub


Private Sub CustomerSearch_Click()
???
End Sub
