I didn't understand how smartgrid was using request.args which was my main problem. Now that you and massimo pointed it out i've played around and see what is going on. I've got 3 grids in 1 page editing a bunch of tables in a controlled fashion with just a few lines of code. not bad web2py.
Thanks for the response.
