undefined method `calendar_date_select_tag'

Hi,

I am trying to use the 'Calendar Date Select' plugin (http://calendardateselect.googlecode.com/svn/tags/calendar_date_select/).

I've copied all the necessary files (javascript + css + calendar_date_select.rb and so forth files). Further, I added <%= calendar_date_select_includes "blue" %> line of code in my layouts/application.rhtml and finally restarted my Apache server.

But I keep on getting: undefined method `calendar_date_select_tag' when I try and use this method in my View.

Any ideas so as to what I might be missing? Any help greatly appreciated. Thanks.
