Add Heading Before dynamically created form field Jquery .insertBefore
Looking at your page, I don't see where #price is defined. Maybe it is added later via JS and i missed it..
You are using jquery in no-conflict mode, and you need to wrap your code in document ready..
<script type="text/javascript">jQuery(document).ready(function() { jQuery('<h5 class="form_title">Calculate Return</h5>').insertBefore('#price');});</script>Running this; however, has no affect on the page(from what i can see).
The code below works because the ID exists. It isn't what you are trying to accomplish, but it should get you started.
<script type="text/javascript">jQuery(document).ready(function() { jQuery('<h5 class="form_title">Calculate Return</h5>').insertBefore('#property_name');});</script>
