"dtml-in" iterates over the objects. In each iteration, "dtml-in" exports the current objects attributes into the namespace. Thus, "seq", "vid", ... are probably attributes of your objects.

id=&seq=&vid= where can i find out more about these properties, i.e. the seq...vid... and so on..? thanx for any directions in advance, later, amoebia VCN - The Leader In Corporate Communication Solutions Visit our website at http://www.vcn.com.my. or http://www.vcnlinux.com ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

A minor clarification of terms: * *acquisition* acquires attributes/methods form containing objects or the context of the objects use * DTML methods usually are passed a *namespace* containing name->value bindings. This namespace contains many variables, REQUEST and its content, acquired attributes/methods, variables made available with , , , ... Z SQL methods do support acquisition. They are, however, not called (automatically) with the current namespace but only with the REQUEST object. Thus, they can automatically use only acquired attributes/methods and variables contained in REQUEST but not the variables defined in an enclosing DTML method (via with, let, in, tree ). Acquired attributes do not need tp be listed in the "Arguements" property of the Z SQL method, REQUEST variables have to.

Re: [Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
this should work too (untestet):
id=&seq=&vid=
('id' var should be put on the namespace by 'active_category_method()'
and gets passed in to 'category_method()' (which, being a zsqlmethod,
wouldnt take a var from the namespace)

RE: [Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
THANKS A TON!!! I just found that the following solutions works also: I think the only difference is the id is evaluated in the namespace variable before invoking the SQL_METHOD id=&seq=&vid= or id=&seq=&vid= Your point on the SQL_METHODS is a good one! I had no idea! Theodore E.

It bites everyone who uses SQL methods eventually. ZSQL methods do not perform acquisition, but will look at REQUEST, change it to. id=&seq=&vid= If you have a lot of arguments that need to be captured, you can build a DTML Method, say setup_category_method_parameters that has these builds the REQUEST. Then your dtml can look like: id=&seq=&vid= > > Thanks in advance! > > Theodore E.
