[Zope] dtml-if fustration!

[Ausum Studio]

What is the "next pass"?. Do you mean within the same page?
If so, you don't need to declare the variable, as long as it's been already
defined for the whole page. Just use <dtml-var SelectSID> anywhere.

Now, if you need to change its value, and then use it on the remaining
portion on the rendered page, the anwser is the same, use <dtml-var
SelectSID>. You don't need to use the "REQUEST.SelectSID" part.
