How do I show calendar events for a single category?

<MTCalendar category="<$MTArchiveTitle$>"> just spits out a bunch of "> throughout the calendar.

However, placing <$MTArchiveTitle$> before <MTEntries..> shows the category just fine. Ultimately what I want the output to be is <MTCalender category="Bells"> for example.

Am I just using the wrong tag?
