I also got it working whit some help from u4ia from www.mirc-helpdesk.

This is what i have now:
Code:
 On 1:text:Bartender *:#:{
if (cola isin $1-) { 
var %nicknum = $nick($chan,0) 
var %nick1 = 1 
} 
while (%nicknum >= %nick1) { 
if ($nick($chan,%nick1) isin $1-) { 
var %nicklijst = $+(%nicklijst,$chr(32),$nick($chan,%nick1)) 
} 
inc %nick1 
} 
$read(bar\cola.txt,t)  $+ %nicklijst
}
