Clicking an element within an iframe

I need my BOT to read the data of an element, and click on a button of another element, that are inside an iframe. I work with Softomotive's P192.168.1.254 rocess Robot. The problem I am having is that when I try to scrape the CSS element that I need, the Control section of PR reads up until the iframe only, so the process cannot perform the individual operations that it needs to.

Has anyone had the same problem before?
