[Zope] Zope ORB question

[Pedro Lima]

I'm still trying to understand the ORB mapping in Zope. 
I tried to do the following

1) call a document with http://localhost/zope/test?tipo=5

and now 'tipo' is variable of document 'test' 

2) in document 'test' I make a query in a database and I put
everything in a select box

<select name=test>
<!--#in query_test-->
<option value=<!--#var tipo_id-->>
<!--#/in-->
</select>

OK. This works. But if i want to put the option 'tipo' selected? This
code fails because tipo is not in the query_test object. Is it
possible to get the 'tipo' value inside the 'query_test' object?

<select name=test>
<!--#in query_test-->
<option <!--#if expr="tipo_id==tipo"> selected                
<!--#/if-->
 value=<!--#var tipo_id-->>
<!--#/in-->
</select>

Thanks for your attention
