Calendar unmodifiable

Hey,

I’m trying to change the view of my calendar, actually I want to use an ajax calendar plugin. I found 2 of ’em, but everytime I load the ajax calendar plugin, it show me nothing but the default wordpress calendar (see it here, on the right)

I’m sure that I installed the plugins correctly. And I’m sure that I’m writing the right tag, for example one of the plugins work with ajax_calendar tag, but what I see is the default calendar once again.

Please help. It seems that everybody’s happy with their plugins, except me.
