[web2py] Pagination [Web2py Utils] returns None

[Andrew Evans]

Hello I am trying to create some pagination on my comments page everything
seems to be working, however when I click the next link it goes to a page
that all it says is None

Anyone know why this is happening and how to fix it

There are entries in the db.

Thanks in Advance

below is my code

*cheers


def product_wall():
    this_page = request.args(0)
    product=db(db.product.id == this_page).select(db.product.ALL)
    for products in product:
        #comments=db(db.comment.product == this_page).select(db.comment.ALL)
        comments=db.comment.product == this_page
        orderby = ~db.comment.id
        pcache = (cache.ram, 15)
        stars = StarRatingWidget(single_vote=True)
        db.comment.rating.widget = stars.widget

        db.comment.product.default = products.id
        form = SQLFORM(db.comment)
        db.comment.product.id = products.id
        if form.accepts(request.vars,session):
            response.flash = 'Your Comment has been submitted'
            paginate =
Pagination(db,comments,orderby,display_count=2,cache=pcache,r=request,res=response)
            rows=paginate.get_set(set_links=True)
            return dict(comments=rows,form=form,products=products)
        elif form.errors:
            response.flash = 'Please correct your error'
            paginate =
Pagination(db,comments,orderby,display_count=2,cache=pcache,r=request,res=response)
            rows=paginate.get_set(set_links=True)
            return dict(comments=rows,form=form,products=products)
        else:
            paginate =
Pagination(db,comments,orderby,display_count=2,cache=pcache,r=request,res=response)
            rows=paginate.get_set(set_links=True)
            return dict(comments=rows,form=form,products=products)
