Hello @clintonpratt,
Support portal is there on the main website https://www.divimode.com and I see that the following response is given against your ticket.

Hi Clinton
Our JS API is tailored towards developers who know how to implement custom logic into the plugin, and we do not provide custom code support with the free plugin.
However, your required feature is already included in our premium plugin Divi Areas Pro, so I suggest giving it a shot. As mentioned, you do not need to change anything, but only install and activate the plugin.
About that page: I’ve tested it, and I can see the calculator when I let the page load in the background – i.e., open the URL and instantly switch to a different browser tab. After 3-4 seconds, switch back to your website tab and open the Popup; now, you can see the calculator. But when you keep the website visible while it loads, the calculator does not work. Most likely, the reason is that background tabs load slower, and scripts are executed in a different order.
