yes ..

okay here is my init event:

on *:dialog:goop.di:init:*:{
if ($_goo.r(goop.mp3dir) == table does not exist) { _goo.w goop.mp3dir $sdir(C:\,goop - choose mp3 directory) }
%temp = $findfile($_goo.r(goop.mp3dir),*.mp3,0,did -a goop.di 1 1 $1-)
mdxinit
mdx SetControlMDX $dname 1 ListView report rowselect flatsb single grid editlabels headerdrag > C:\goo\core\dlls\mdx\views.mdx
did -i $dname 1 1 headerdims 309 50
did -i $dname 1 1 headertext filename $chr(9) time
;did -a $dname 1 1 iio - rapture (riva remix) $chr(9) 5m32s
}

maybe that will help you more.
$_goo.r(goop.mp3dir) returns the mp3 file path.
