I am unable to open the database at this time. I'm assuming that your reference to "box" in your question refers to a combo box. If that is the case, why don't you create a separate form for each of these situations. Then, based on the selection in the combo box, just change the subforms SourceObject
Private Sub cbo_YourControlName_AfterUpdate
IF me.cbo_YourControlName = "Clients in the Fund" Then
me.subFormControlName.SourceObject = "frm_Clients_in_the_Fund"
Else if me.cbo_YourControlName = "Contacts with Manager"
me.subformControlName.SourceObject = "frm_Contacts_with_Manager"
Else
me.subformControlName.SourceObject = ""
End if
me.subformControlName.visible = (me.subformControlName.SourceObject <> "")
End Sub
You will need to replace "subformControlName" with the name of the subform control on Form10.
