Can't display multiple selection fields in additional memberlist

[BWJ]

Idea: To make an additional member list page showing some specific custom profile fields
What I have done: I have simpy copied the relevant templates and memberlist.php
Status: Everything seems to working fine except for one thing. I'm only able to show following type of fields:

single selection menu
single line text box

With the code:

	<if condition="$show['customfields']"><td class="$bgclass">$userinfo[fieldX]</td></if>

in memberlist_resultsbit_Newtemplate

I simply can't get it to work with e.g. the multiple selection menus.

Any help would be very appreciated
