>Is there a way I can have stand_alone pass values back to my formset?

Hmmm - that sounds like a little bit of a messy framework :)

But, there are a couple ways to do what you need. A simple technique is to launch the child form with a NAME clause, with a formset property. For your case, create a formset property something like Childform. Now launch the stand alone child form like this:

DO FORM MyChildFormName NAME thisformset.Childform

Now the stand alone form is an object of the formset (sort of a temporary virtual formset form), and you can access the formset from the stand alone form directly, like

myformsetSCXname.myproperty = ...

or

myformsetSCXname.form12.something = ...

or call a method

myformsetSCXname.mymethod()

all direct assignments/calls from the child stand alone form, if you see what I'm getting at here.
