var selectedValue = $("input[name=form]:checked").val();

You should do it like this:

var radio = jQuery('input[name="form"]:checked');

You can then retrieve your radio value or other attributes:

var value = radio.val();

It's a good idea to see if any radio is checked before doing that:

if (radio != undefined)
{
    //do what you need to
}

Alternatively, you can also try this - 

    $(".modal-body input[type=radio]").each(function(){
        if (this.checked)
        {
            console.log(this.value+" is checked");
        }
    });

var myval = $("#myForm input[type=form]:checked").val();

I would put in a div (id=myForm) and call it in the safety of the parent, just in case you have anything else on the page, like a newsletter signup or search box with options.
