Javascript not parsing

Hi -

I have a HiddenSelectQuestion component that contains a set of hidden 
elements.  I want a javascript function that sets the value of the named 
element.  I have debugged this as straight HTML to make sure the Javascript is 
valid.  However, Tapestry gives a parse error.

The script is at the bottom of the email.  The Tapestry parser does not seem 
to like the '<' in the while statement and gives the following exception...

   net.sf.tapestry.ApplicationRuntimeException 
   Unable to parse script 
       /com/informative/study/jwc/HiddenSelectQuestion.script. 
   
   net.sf.tapestry.util.xml.DocumentParseException

I am using Tapestry 2.2 in JBoss 3.2 Beta 2.  Any pointers or suggestions 
would be greatly appreciated!  Thanks...
