[Zope] skinscript and URL traversal question

[Aaron Payne]

Hi all,

I'm using a zsql method in a skinscript with query ... compute ... and it 
mostly works.  Calling the dataskin where the id is part of the query 
string  (coupon id=977931214.694) works.  For example,
http://CouponSite/CouponManager/CouponAttributes?Cid=977931214.694

Where:
CouponManager is a specialist
977931214.694 is the id of the coupon
CouponAttributes looks up the dataskin with:
<dtml-with "getItem(Cid)">
   <dtml-var couponattributes>
</dtml-with>


Trying to access the object directly through URL traversal fails.
http://CouponSite/CouponManager/977931214.694/CouponDetails

Where:
CouponDetails displays the coupon attributes with:
<dtml-var couponattributes>

It returns a not found error.  The CouponManager specialist can't find the 
coupon 977931214.694.

Any thoughts why this is so?

SkinScript Trigger:
WITH QUERY searchByNameCheck(self.id) COMPUTE 
name,username,coupon_text,categorylist,categoryheader,expirationdate,status,couponterms

PythonMethod:
searchByNameCheck
<params>self,name<params>
Cname=name
result=self.searchBy_Name(name=Cname) #zsql method
return result
