I have a little invoice page in my app, but i also want people to be able 
to invoice as many things as possible at once without having to keep saving 
so many times, this is what i used:

*MODEL*
db.define_table("invoice", 
                Field("product", "list:string"),
                Field("price", "list:integer"),
                format='%(product)s')

In my view i want these details displayed in an html table but they appear 
in list format, how do i remove them from the list to display them 
individually na d how do i sum up those in my price field?
