Trying to get a form to load pages with the previously checked radios already checked (upon a fresh load).

The submissions of that page are held as php variables which I can pass into the javascript, the rest should be simple, but it's not working for me.

My code:

```
<div class="question">
            <label for="sv_213">Question?</label> 
            <input 
                    class="radio"
                    type="radio" 
                    value="Yes" 
                    name="sv_213" 
                />Yes
            <input 
                    class="radio"
                    type="radio" 
                    value="No" 
                    name="sv_213"
                />No

        </div>

```

My javascript:

```
$(function() {
    var $213 = Yes;
    $("input[name='sv_213'][value="$213"]").attr('checked', true);

    });?

```

In the above js the

```
var $213 = <dynamically generated content>

```

Such that it is set equal to the value of the radio button that was checked

Here is a js fiddle with it not working:

Many thanks for any help.

Incidentally my code is based on this, previously asked question:
