Adding Javascript (chat code) to iframe

I’m working on http://helpflow.net/preview/.

The iframe popup works exactly as needed. I used the below to link including class=”fancybox-iframe” as instructed.

<a class="fancybox-iframe" href="http://www.executane.com">Click Here to see a preview</a>

But I want to add the below website chat code so that it shows up on the iframe on bottom right of window (i.e. bottom right of iframe, not bottom right of the website being i framed).

What file in plugins folder do I edit to make this happen? What do I need to input?

Been troubleshooting all morning with adding the code in various places, adding it as chatcode.js to the plugins folder and then calling that, with no success. I’ve cleaned up everything along the way so there’s not hacking of the code left in there, but I can’t figure out how to make this happen.

* Please note the chat box you see at the bottom of your browser (not the bottom of the iframe) is not the chad code powered by the inframe- it’s on each page of the helpflow.net website. Yes, I want the same chat code to appear within the iframe (i’ll be removing it from this page of help flow in the future.

Thanks!
