HTML and Script optput not show in wordpress theme

[nasavsisro]

hi i'm using custom theme option framework on my theme i have been integrated every thing but in textarea when paste and try to save option it automatic remove HTML codes and <script> only text and <> are remain. i don't know how to resolve this problem.

also there is default google tracking code option it was working when i explore source of function i found this:

/* ----------------------------------------------------------------------------------- */
    /* Show analytics code in footer */
    /* ----------------------------------------------------------------------------------- */

    function wrockmetro_analytics() {
        $shortname = wrockmetro_get_option('of_shortname');
        $output = wrockmetro_get_option($shortname . 'wrock_analytics');
        if ($output <> "")
            echo "<script type='text/javascript'>" . stripslashes($output) . "</script>\n";
    }

    add_action('wp_footer', 'wrockmetro_analytics');

**Textarea code from OptionInterface.php**

// Textarea
            case 'textarea':
                $cols = '8';
                $ta_value = '';
                if (isset($value['options'])) {
                    $ta_options = $value['options'];
                    if (isset($ta_options['cols'])) {
                        $cols = $ta_options['cols'];
                    } else {
                        $cols = '8';
                    }
                }
                $val = stripslashes($val);
                $output .= '<textarea id="' . esc_attr($value['id']) . '" class="of-input" name="' . esc_attr($option_name . '[' . $value['id'] . ']') . '" cols="' . esc_attr($cols) . '" rows="8">' . esc_textarea($val) . '</textarea>';
                break;
