Hello Manny,
I’m not sure i understand your use case. Why do you need a dynamic page to be opened in an iframe ?
You can try adding an html component (= iframe) and setting it to show the url of your dynamic page, either statically via the component’s settings panel, or dynamically by changing it’s “src” sttribute (https://www.wix.com/code/reference/$w.HtmlComponent.html).
