How do I change an objects value type depending on a Y/N Radio button?

I have the following code behind some Radio Buttons:

Form1645.Page3.TeeCrossSubform.TeeCross::exit - (JavaScript, client)

if Page3.TeeCrossSubform.TeeCross.rawValue = "N" {

    xfa.Page3.TeeCrossSubform.Disruptfield.access = "open";

    xfa.Page3.TeeCrossSubform.TeeCrossCC.access = "protected";

    }

else{

    xfa.Page3.TeeCrossSubform.Disruptfield.access = "protected";

    xfa.Page3.TeeCrossSubform.TeeCrossCC.access = "open";

    }

NOTE: I based this code on the following information (which may be wrong but I found nothing else on the subject): http://forms.stefcameron.com/2010/03/08/disabling-all-fields-within-subform/

No matter which radio button is selected (Y or N) the fields are all "open" or "unprotected".

Any help is greatly appreciated!
