im using this code:

alias serverpopup {
var %i 0
var %t $scon(0)
dll popups.dll New Sound 12 12
dll popups.dll LoadImg Sound icon normal icons\server.ico
while (%i < %t) {
inc %i
dll popups.dll AddItem Sound 0 0 $scon(%i) $+ . $scon(%i).server $cr ok
}
var %do = $dll(popups.dll,Popup,Sound [ $mouse.dx ] [ $mouse.dy ] )
var %com = $gettok(%do,4-,32)
echo -a $dll(popups.dll,GetProperty,sound 1 text)
;scid $gettok($dll(popups.dll,GetProperty,sound 1 text),1,46) /window -a "Status Window"
}

where it has echo -a $dll(popups.dll,GetProperty,sound 1 text)

how can i change the 1 to the selected line from the popup ?
