I have inherited a mess.
A MS Access app (ADP) with many many nested forms.

In this wuestion I have

Parent Form
      SubSubForm on SubForm

On the parent form I have a combobox (cmbVisits)

On the ParentForm cmbVisits_Change() event I want to
execute a public sub on SubForm
execute a public sub on SubSubForm

I'm able to execute the sub form public sub with this...

I've tried all kinds of permutations of the sub sub form
Like this one...all with a object error message

You will have to provide more details.

Is the SubSubforms actually nested inside the SubForm, or are there just two subforms on the main form?

What are the Control Names of each of the subform controls (don't confuse this with the value in the SourceObject property of each item.

You might have to declare that function (in the code section of the SubSubForm) from Private to Public.

As mentioned above, make sure you are using the "control names" and not the "source Object" to refer to these subforms.

On the main (ClientVisits) form is the combobox
This same ClientVists form has 3 sub forms...and the first one has it's own sub form

1. MarketingVisitationClient
     a. MarketingVisitationClientContactsWorklist
2. ClientVisitContactEvent
3. ClientVisitsNearbyLV

I can execute the public sub on #2 with

I am trying to execute the public sub on 1.a. named loadContactData

It IS a public sub in the sub sub form.

Public Sub loadContactData()
        Dim cmd1 As New ADODB.Command
        Dim rst1 As ADODB.Recordset
        cmd1.ActiveConnection = CurrentProject.Connection
        cmd1.CommandType = adCmdStoredProc
        cmd1.CommandText = "usp_MarketingVisitContactsGet"
        cmd1.Parameters("@VisitID") = Nz(Me.Parent.cmbVisits, 0)
        cmd1.Parameters("@ClientID") = Me.Parent.txtClientID 'Me.Parent.Parent.getClientID()
        Set rst1 = cmd1.Execute()
End Sub

That error makes more sense now.

Your line 9 refers to "me.Parent.cmbVisits"  but that combo is not in the parent form, it is in the parents parent, so try:

cmd1.Parameters("@VisitID") = NZ(me.parent.parent.cmbVisits, 0)

Put a breakpoint in the LoadContactData subroutine and confirm that those parameters are being  set correctly.

I know I'm missing something obvious (Like I just missed the Parent path)
I'm frustrated with myself.

But it's still not getting to that breakpoint...tried that myself previousely

Getting this error screen now

1.  Are you certain it is running the other code (loadQuestions).  Have you put a breakpoint in that code and stepped through it?

2.  Are you certain that subform is actually loaded at the point where this occurs?  Instead of trying to run code on that subform, try popping up a message box with the value in one of the controls on that subform.

msgbox me.MarketingVisitationClient.form.MarketingVisitationClientContactsWorklist.form.txtSomeControl

I must admit that I have never felt the need to call a subroutine nested in the code module of a sub-sub form.  Is there a reason that this code could not go into a general code module, rather than a forms code module?

Is there a reason you could not call that procedure from within the LoadQuestions subroutine of the MarketingVisitationClient form?

Well...this entire forms set is part of a much larger Client Visits and Schedu;ing process.

I must admit, it's been years since I was in MS Access.  been in AJAX .Net Web Forms and WinForms until this recent job.

The forms are all datasheet views so it's functioning like a hierachy based set of GridViews

Without going into the gory details...
I can't just use a view etc to call in the data.

These forms are all filtered by the Combobox.

How would I do that on my sub_sub form based on the conbobox click...using a general code module?

If I go to the sub sub form and put in the stored procedure I can then open the form and (since there are two paramaters to the stored procedure  @ClientID and @VisitID) ...
I can manually enter a ClientID and a VisitID and get the data.

Is there any way to tie that stored proc to the Parent.Parent.Combobox?

  Everything you've pointed out to me is correct.  

I know for a fact it works because I've done it in a second database with a similar setup.

There's just something in this particular database that isn't working.

Since your reply 38724563 was what worked in a second database I'll accept that.

Looks like I'll have to find a work around.
