I get the following error with this code...
"SyntaxError: widget cannot determine options of
page_articles.placement" - Line 64 of Default.py
---LINE 64 IS LABELED---
def page_creator():
response.title = "Page Creator"
if len(request.args):
pages = db(db.page_articles.id==request.args[0]).select()
if len(request.args) and len(pages):
page_form = SQLFORM(db.page_articles, pages[0], deletable=True)
else:
page_form = SQLFORM(db.page_articles)#<--- This is line 64
if page_form.accepts(request.vars, session):
response.flash = 'Action Commited Succesfully'
elif page_form.errors:
response.flash = 'Hmmm, something went wrong.'
all_pages = db((db.page.id==db.page_articles.page) &
(db.article.id==db.page_articles.article))
return dict(page_form=page_form, all_pages=all_pages)
----
And what you gave me...

> existing =
> db((db.page_articles.page==request.vars.page)&(db.page_articles.placement==request.vars.placement))
> db.page_articles.placement.requires = [IS_IN_SET(range(1,21)),

Thanks for the help,
Jason
