Embedding a Qualtrics Survey using iFrames

Hi Everyone, I am trying to embed my survey into a community platform called CMNTY using iFrames. The first page of the survey appears fine but when I try to move on to the next question I get the error code in the image below. ! CMNTY have a function to generate the iFrame code and it looks like this - <div class="redactor-iframe js-redactor-iframe noneditable"><div class="settings">{IFRAME}[{"url":"https://xxxxxxxxxxxxxxx"},{"username":"CMNTY:username","userid":"CMNTY:userId"}]{/IFRAME}</div></div> As I say, the first page of the survey appears fine, it is only after I click the next question button that I receive the error. I have also noticed that I am not able to open a hyperlink I have on the first page either. I would appreciate any help you could offer Thanks, Pete
