Need help with my iframe code

[marymary61]

I am trying to make this iframe code work, but no matter what I do, it doesn't seem to work. Suggestions?

<iframe src="http://www.secure-booker.com/synergysportstherapy/BookOnlineStart.aspx" width="100%" height="550" style="border:none;"></iframe>

Is this on your live site or just in the editor? It's not unusual for an iframe to not load anything in the editor (for security reasons), but load fine on a live site.
