The correct answer is #3.

you can look at each page of a pageframe of a separate (but related) form.

Since you already have one of the forms you would like to have on a page of a pageframe, you might well save considerable time by:

1) Opening that form in the Form Designer.
2) Opening a new form with the Form Designer and placing your pageframe and page(s)on it.
3) Select all objects on the existing form (#1 above) and copy to the clipboard.
4) Now move to the new form, ensure that the page of the pageframe is selected, then paste. All of the controls from the first form will end up in the page along with any attached code.
5) But you will still have to take care of any FORM method code you had in the original form as well as revising any references in the pasted methods to properly refer to the newly introduced pageframe/page container hierarchy. For instance, something that previously said THISFORM.xxxxx will now have to resolve to THISFORM.PgF1.Page01.xxxxx.

good luck,
