Try:
Code:
If IsNull(Me.txtSearch) = False Then
Me.RecordsetClone.FindFirst "[AcctNum]=" & Me.txtSearch
If Me.RecordsetClone.NoMatch Then
MsgBox "No record found", vbOKOnly + vbInformation, "Sorry"
Else
Me.Bookmark = Me.RecordsetClone.Bookmark
End If
Me.txtSearch = Null
End If
Is AcctNum a text type field? If so:
Me.Recordset.FindFirst "[AcctNum]='" & Me.txtSearch & "'"
The subform should be linked to the main form and therefore cannot display any record that is not associated with the main form record.
