Typing something into the form text-boxes below and submitting it does the following:
1) updates the second cell text - adds a pink background
2) updates a database back at the server with both pieces of data.
3) receives a confirmatory response from the server, then updates the second cell text to a green background.

Also, clicking on the first cell, updates the 2nd cell with the text in the first input fields, and the 3rd cell with a fixed string.

This will be useful!
