I am running version 5.6.2.1.

I want to create a form to interact with database tables I have created manually. The existing documentation on the concrete5 formhelper is sorely lacking.
http://www.concrete5.org/documentation/developers/5.6/forms/standar...

There is only enough information to create a form which looks nice and does nothing. The documentation of behavior of formhelper when a form is submitted apparently doesn't exist. Does anyone know of documentation on how a formhelper actually behaves? I.E. how is the form action configured through a formhelper.

If not, any examples of formhelper used in blocks or single pages would be helpful.
