Additional Text Under Submit Button

Yes, it is possible to have text under your submit button.  

This is under "Additional Text".  You will click into your step, scroll down, and find the "Additional Text" section.

In this box, you will adjust the color and the text that will appear under the submit button.  This is the custom code here:
<p style="color:#000;"> write text</p>

The #000 is the hex code for your color.  #000 represents black.  Here is a website that will allow you to find the hex code for the color you prefer: https://htmlcolorcodes.com/

"Write text" represents the place in which you will type the text that you would like to appear in your Leadform.
