please look at this in the edit view as the code fragment is different from what is displayed in the plain wiki page
Comment by chibaguy: I suggest using the IFRAME wikiplugin. This works without a problem in Tiki 2.1 at least. See http://zukakakina.com/IFRAME_plugin_test, where I used your data but put it in the plugin. Only wiki syntax is used, no HTML. There seems to be a problem with the map info loading slowly, though, but this was mainly a test of the iframe that contains it. The iframe plugin is available here.
