Embed KML Viewer in vB4?

[SurfTalk]

Puuurllease help me with this! No answers on vbulletin.com, so I'm hoping someone here can help!

I'm trying to embed a KML viewer in a CMS article on vB4.
I know the Viewer works, as if I embed the code, in for instance my blogger account page, it displays both the google earth viewer and all the detail from the KMZ/KML file fine.

If I create a widget in vB4 and use this code, it also displays fine. The problem is I don't want the KML viewer in a widget, I want it in an article!

When I create an article, nothing is diplayed at all. I've checked permissions, and as an admin I can create html so thats not the problem. If I wrap the embed code in CODE tags, the viewer displays (with all the correct data) but it's inside the tiny code box so it isn't usable. Can i make the code box bigger? Is there some other way I can get it to display? I'm assuming that I've made some dumb error in a setting somewhere but I can't track it down. Please help!
