iframe not embedding (Responsive theme)

Hello

I have created a landing page (using ClickDimensions)but it is not embedding properly. I use the Responsive theme.

This is the iframe code I have copied in: <iframe src=”http://web.trevor-roberts.com.au/trevor-robertscomau-azjg3/pages/24478ac38915e611813ac4346bade5b0.html&#8221; allowtransparency=”true” width=”100%” height=”500px” type=”text/html” frameborder=”0″ style=”border:0″></iframe>

Here’s what the page preview looks like: http://www.trevor-roberts.com.au/download-restructure-workbook/?preview_id=772&preview_nonce=16af89249e&preview=true

I get an error message saying unable to resolve DNS server address.

I have installed and activated the iframe plugin but it is not making a difference.

I am very new at this and would like to know how to fix this.

Thanks!
