Need Help with Some PopUp Pro Settings

I need some help with a few settings. I have a pop up with an iframe that displays an html website that I have located on the same server. (I am using Advance iFrame plugin.)

I need vertical scrollbars, but they are not showing up on longer pages.

I don't want horizontal scrolling bars because I want the width of the pop up to be wide enough for the width of the site.

Also, the pop up window isn't acting responsively.

Here's the page with the pop up:

I've also granted access if you prefer to do it that way. That would, of course, be better for me :slight_smile:
