[CUSTOM CODE REQUEST] Just trying to trigger a lightbox with a button (using Aweber)

Not sure how to code the html button to achieve the final result – email pop up triggered upon clicking a button.

Here’s the guide I’m following: https://help.aweber.com/hc/en-us/articles/204027876-How-do-I-trigger-a-lightbox-form-with-a-link-or-button-

Can you help me through this process to set it up so that it is up and working.

I also found this guide : Button to popup Aweber form | Web Hosting Talk

But not sure how or where to put the code, and make sure that it is in the actual header/body.

Tried a bunch of things, but nothing I’ve tried is working.

Help :confused:
