i made an edit using this
if (($did == 4) && ($did(6).sel)) { did -ra $dname 9 $address($did(ban_assist,4).seltext,$did(6).sel) }
if ($did == 6) { did -ra $dname 9 $address($did(ban_assist,4).seltext,$did(6).sel) }
and worked
by the way, would be a nice idea, if there is a combo to choose the rooms =)
