ReCAPTCHA library - ignited

[eluser]Unknown[/eluser]
I can't get the reCAPTCHA widget to display on my form. The registration page loads just fine. But, for some reason, no variables are being passed from the reCAPTCHA library to the view that has the reCAPTCHA field code.

Here is my controller (the pertinent parts):

Code:

$this->load->library('recaptcha');
    $this->load->library('form_validation');
    $this->load->lang('recaptcha');

    // Validate form
    ...
    $this->form_validation->set_rules('recaptcha_response_field','Captcha','required|callback_captcha_check');

And I've tried loading the field view as a variable:

Code:

$data['recaptcha'] = $this->load->view('recaptcha',$data,true);

And within my main view:

Code:

<?php $this->load->view('recaptcha');?>

Here is the view code:

Code:

[removed]
      var RecaptchaOptions = {
        theme:"<?= $theme ?>",
        lang:"<?= $lang ?>"
      };
    [removed]
    [removed][removed]
    <noscript>
            &lt;iframe src="&lt;?= $server ?&gt;/noscript?lang=&lt;?= $lang ?&gt;&k=&lt;?= $key.$errorpart ?&gt;" height="300" width="500" frameborder="0"&gt;&lt;/iframe><br/>
            &lt;textarea name="recaptcha_challenge_field" rows="3" cols="40"&gt;&lt;/textarea>
            &lt;input type="hidden" name="recaptcha_response_field" value="manual_challenge"/&gt;
    </noscript>

When I access the registration form, the page loads but the reCAPTCHA widget doesn't show up because it throws an error for every variable -- all are undefined.

I'm sure this is something basic about loading variables from a library into a view. Can someone help me out?
