newbie question about eruby

Hi Group, I have a question about eruby. I keep getting the following 
error. I get the same error in apache error log when I try to view it in 
firefox. How do I fix it:

eruby pique.rhtml
pique.rhtml:1: undefined method `form_remote_tag' for main:Object 
(NoMethodError)
--- generated code ---
print(( form_remote_tag :url => { :action => 'whet' } )); print "   \n"
print "Enter your name: "; print(( text_field_tag :name )); print " \n"
print(( submit_tag "Greet Me" )); print " \n"
print(( end_form_tag )); print " \n"
print "<h2 id=\"greeting\" style=\"display: none\"></h2>\n"
