Submit message in a Lightbox

Hello!

I'm not a programmer but I'm trying to create a website on Joomla, using Chronoforms as "Quick order" tool.

The form works fine but I want to make some modifications:

1. The page should not restart after the form was submitted;

2. "Thank you" message should appear in the Lightbox window.

I've created a code of the link but Idon't know how to connect it to the Chronoforms.

Please help.

Thank you.

Code
<div style="display: none;">
<div id="thank_you" style="width: 460px; height: 150px; color: rgb(0, 0, 0); overflow: auto;">
<p>
 </p>
<p align="center">
<strong><font color="#ff6600"><font size="4">Thank you for the order</font></font></strong></p>
<p align="center">
<font size="3">Our specialst will contact you</font></p>
</div>
</div>
<p>
<a data-lightbox="" href="#thank_you">Link</a></p>
