Rails - Feb 2006 - acts_as_taggable

does anyone now how to delete tags. The code below doesn''t seem to work

def remove_tag
    	@page = Page.find(params[:id])
    	@tag = Tag.find(params[:tag])
    	arr = @page.tag_names
    	arr.delete( @page.name )
    	@page.tag( arr, :clear => true )
    	@page.save
    	render( :partial => ''show_tags'' )
    end
