jQuery not() selector problem
<p>I have a depended radio groups, where by clicking on input#radio10, input#radio16 .form-block-cms should slide down. And no problems with that.</p>

<p>Problem is when I select input#radio16. form-block-cms slides down and back up straight away. I tried to use cond statements else if input#radio16 not selected, but it is still doing this.</p>

<p>How can I get around it please?</p>

<pre><code>if ($('input#radio10, input#radio16').is(':checked')) {
    $('.rsform-block-cms').slideDown().addClass('additionalField')
}
else if ($('input#radio16').not(':checked')) {
    $('.rsform-block-cms').slideUp();
};
</code></pre>
