Bob - We are all trying to help you do something that is really not that hard.

In the example I posted, as I tried to explain, I copied the code from the Zillow site you linked to.

In Xara, I created a rectangle to the same size as was referenced in the code, then with the rectangle selected, I went to Website Properties (the blue globe icon on the Infobar) > Placeholder > Replace with HTML Code section.

I clicked on the button that reads HTML Code (body) and pasted the code into the window.

Now this next step is important and I left it out of my previous response.

Click Apply. This step is critical. If you don't press Apply, nothing will happen.
