I'm using Knockout.js attached to a couple radio buttons.  When one is selected, it changes a specific set of controls for that selection.  I need to validate the values for one of the selections (Ambient Temperature).

So when Ambient is selected, it displays a text box to enter a temperature, and a couple radio buttons for Celsius and Fahrenheit.  I need to require the temperature and a temperature unit (C|F).

My fiddle has it basically working, except for some reason my jQuery Validation code produces an error so it doesn't validate or save.  I'd appreciate it if someone can update my code to make it validate the data, and explain what you did.

Again I appreciate the assistance.
