Output is code and displayed as text

Regardless of whether I choose “output=”text”” or “output=”html””, my output, which is an iframe embed code, is simply being displayed as code on the page, rather than the iframe showing as the code directs. Is there any way to get this output to be displayed correctly, and for the code to be read and parsed by the browser to display what I need it to?
