PTVs are before if. The markup expression appears to be after the PTV.
{$var} >$[phrase] B=>>
{( >{$var} B=>>>
fulltext >_begin B>
&amp; <& B>=<<
& <if B>=<
if fulltext B>=
I made a custom page var for the YYYYMM that the markup expression was
returning. That seems to have worked. Not sure why this PTV lookup failed
silently though...
