One cannot use (:if:) directives to conditionally set page text
variables. When PmWiki goes to read the value of a page text variable
from a page's text, it doesn't try to evaluate the other markups
on a page, such as (:if:). It just looks for things that match
the page text variable patterns, and returns whatever it finds.
Also, this probably is unrelated, but in general you would want
to write
(:if equal "{$:flag}" "yes" :)
because otherwise an empty $:flag variable wouldn't appear in the
(:if:) directive.
Hope this helps,
Pm
