[horde] 2 selections from DropDown in a prefs as default in prefs.php

[Stefan Johänntgen]

Hi,

I found this in kronoliths prefs.php:

// show event location in the calendar and/or print views?
$_prefs['show_location'] = array(
     'value' => 'a:1:{i:0;s:5:"print"}',
     'type' => 'multienum',
     'enum' => array(
         'screen' => _("Month, Week, and Day Views"),
         'print' => _("Print Views")
      ),
     'desc' => _("Choose the views to show event locations in:"),
);


I would like as default "print" and "screen".

How can I change it? I try 'value' => 'a:1:{i:0;s:5:"print screen"}', 
but thats not so easy :-(
