and code behind:

def crearCotizacion():
    materialesT = request.vars.get('TablaMateriales')
    rowsCount = materialesT.rows.count
return dict(rowsCount = rowsCount)

Thank you!

It seems like you are trying to access a client side element ('TablaMateriales') on the server side. You can only do that if you explicitly pass the element back to the server.

And then you would need to manipulate it using something like http://web2py.com/books/default/chapter/29/05/the-views#Server-side-DOM-and-parsing

You could just count the number of rows using JavaScript from inside the view: JavaScript to get rows count of a HTML table
