[AccessD] Referring to a function in a subform

Dear List:
 
Gets me every time.  
 
I want to call a private function in a subform on my main form.  Subform
name is subfrmAccount, main form is frmEditAccounts, function name is
MakeShippingLabelEditAccounts.
 
I've tried a lot of variations like:
 
Me.fldShippingLabel =
Forms!frmEditAccounts.subfrmAccount.Form.MakeShippingLabelEditAccounts
 
with ! and . in various places and nothing works.  
 
The function works fine when I use it in the subform.
 
Help!
