[pmwiki-users] PTV in Page List Template

This here probably needs to be {=$BaseName} not {$BaseName}, but I'm not 
sure if it will work.

For your needs, it may be simpler to add a new custom page variable that 
does your processing outside of the markup:

   $FmtPV['$MyBuPos'] = 'FmtMyBuPos($pn)';
   function FmtMyBuPos($pn){
     $base = PageVar($pn, '$BaseName');
     $ptv = "Bu{$base}Pos";
     return PageTextVar($pn, $ptv);
   }

Then in the pagelist template, use {=$MyBuPos} instead of 
{=$:Bu{=$BaseName}Pos}.
