Use the Value method for form elements.

You need to handle the On_Submit event on the window or form to handle a
form submit.
See docs/user_guide.md the Singleton example shows how to do this or
Tutorial 09

Correct. If you don't handle On_Submit it will actually "Submit" the form
and its values.

In tutorial 09 it demonstrates the the other ways of getting the results by
using On_Submit instead of the form actually submitting.
I added a bit in the user_guide about Inner_HTML, Text and Value. The
"Gnoga Concepts" section of the user_guide will keep expanding over time to
include these types of tips.
