Many thanks for you quick answer - but...

(1) I´m declaring $FmtPV as a global in my cookbook-script (se below).

(2) I think I don´t understand what you are 
saying. :)  I don´t user Markup() to set the 
variable in any way - only to create the function 
that sets the variable.... So where and how should I use the '<{$var}' ?

In short my setup looks like this;

my_cookbook.php
========
Markup('my_function', 
'_begin',  '/\\(:my_function(.*?):\\)/e', 'main_function("$1")');

global $FmtPV;

function main_function( $opts )
{
         { code that set $ToMyVariable to what it should be... }

         $FmtPV['$MyVariable'] = '$ToMyVariable'';

         return;
}
========


In config.php
========
include_once("$FarmD/cookbook/my_cookbook.php");
========


On the PmWiki-page
========
(:my_function:)

{$MyVariable}
========

Thomas.
