properly adjusting radiogroup onchange [SOLVED]

properly adjusting radiogroup onchange [SOLVED]

Hi,

I'd like to change the selected value of a radiogroup once a certain textfield has been focused.

//targetting input with class "field"
$('input.field').focus(function () {
$(this).parent(). //change value...
});

Can anyone help me from here? The idea is that the value in the form actually toggles in the browser.
