Radio buttons, bindings, linking.

ASOC tutorial 2 confuses me. Firstly I can’t take much of the processes in with so much commenting, probably good but my eyes get lost in it. So what I don’t understand is the procedure for radio buttons which I need to now atm and also why there are 2 sets of property e.g. ‘property statusField : missing value’ and ‘property theStatus : “”’ and some talk of bindings, none of which are in the 1st tutorial.

I sort of understand radio buttons now, kinda.
