Getting property value is undefined or null error for JavaScript call in Dynamics CRM 2011

Just started with Javasript + Dynamics 2011 today and got stuck at the beginning itself. I've been trying simple steps as follow 1. Change the value on radio button 2. Call a function from Javascript, which will set two field enabled and disabled

Code is as follows

function navenabled()
{

    var navdata = Xrm.Page.getAttribute("new_currentnavclient").getValue;

    if (navdata == true)
    {
        Xrm.Page.getControl(“new_noofusers”).setDisabled(true);
        Xrm.Page.getControl(“new_navversion”).setDisabled(true);
    }
    else
    {
        Xrm.Page.getControl(“new_noofusers”).setDisabled(false);
                Xrm.Page.getControl(“new_navversion”).setDisabled(false);
    }

}

I'm getting the following error, when changing the value on 'Current Nav Client' field

enter image description here

Also see the steps that I have performed for JavaScript call

Can someone please tell where I'm doing wrong.

What you can try to do is using the document.getElementById ("fieldname").checked property. This value is allways accurate.

First problem is with this line:

var navdata = Xrm.Page.getAttribute("new_currentnavclient").getValue;

getValue is a method, so the right way is getValue()

var navdata = Xrm.Page.getAttribute("new_currentnavclient").getValue();

The second problem is with all the getControl lines, you are using smart quotes

“ ”

Instead you need to use simple quotation marks, so your code will be:

function navenabled()
{

    var navdata = Xrm.Page.getAttribute("new_currentnavclient").getValue();

    if (navdata == true)
    {
        Xrm.Page.getControl("new_noofusers").setDisabled(true);
        Xrm.Page.getControl("new_navversion").setDisabled(true);
    }
    else
    {
        Xrm.Page.getControl("new_noofusers").setDisabled(false);
        Xrm.Page.getControl("new_navversion").setDisabled(false);
    }

}
