Parent or Caller?
If you have "child browses" then the parent is the one calling the children.
If you have a browse on a form then the Form is the parent, and the browse is the child.
In other words, to be a parent the parent is always visible as well as the child.
In your earlier thread you talked about a browse calling a form, and thus being the parent of the form. This is inaccurate. It's not the parent, it's the caller.
