[Zope] dtml-if

[michael]

What am I doing wrong here?

<dtml-var last> -- this prints out the variable sent from last 
(referring) page fine
<dtml-var id> -- this prints out the id of the current item fine


<dtml-if "id == last">  this one!  </dtml-if>

i want this to output "this one!" when the current item is the one 
requested by the last page but they are never seen as == even when the 
two dtml-var are the same

they are never equal! 


thanks,
mike
