Hi. Your DTML method in isTred, <!--#var "'english.'+ _.string.join( _.string.split(URL0, '/')[4:], '.')+'.TR'" --> returns a string. You might want to try changing it to <!--#var "_['english.'+ _.string.join( _.string.split(URL0, '/')[4:], '.')+'.TR']" --> This will use the string generated as the lookup key into the namespace.

Forgive this nagging newbie.

But I am still at a loss and my question seems an eye-opening(at least partially) one for a newbie.

You want <!--#var isTRed--> Quoting the var argument makes it be evaluated as an expression. Not quoting it makes Zope use it by name. If you quote a DTML Method or Document, you must *call* it to get it to render the document. In this case however, refering to the document by name will call the document for you: <!--#var isTRed-->

To restate my question,

The situation: <!--#var isTRed--> just gives the *string* english.members.test.docTest.TR when called in the DTML Document /korean/members/test/docTest not the *value* of english.members.test.docTest.TR (TR is a string property of docTest DTML Document). So, it does not work.

Q0. Is there a way to force an evaluation of the string content of an variable?

Q1. <!--#var "isTRed"--> gives me the source of isTRed method. Is this what you mean by "evaluated as an expression"?

Q2. If you mean using <!--#call --> tag by *call*, call tag gives nothing to the browser, doesn't it?

Q3. <!--#var "isTRed()"--> gives the name error(Traceback is at the bottom), and it seems as expected since the valus of isTRed is just string.

Sorry for any vagueness in my writing. Reading/writing about naming, contents and behavior of OO system in English is far more difficult than I expected.
