ListView Item Selecting

[Anonymous]

Few Questions
1.When you hit print it formats and prints the selected objects names.
Problem:It adds "Ok" to the end of the line and I don't want it to.

2.How do I make the listviews selected item associate with the object array when the button "Select" is pressed. So when Select is pressed it then selects the correct array of objects which are defined at the top in the maxscript file.

rollout rlLights "Light Me Up"
(
 local OutterLights = #($Outter_00,$Outter_01,$Outter_02,$Outter_03,$Outter_04,$Outter_05,$Outter_06,$Outter_07)
 local InnerLights = #($Sphere009,$Sphere010,$Sphere011,$Sphere012)
 
 button btnPrint "Print" width:45 height:14 pos:
 multiListBox mlbxSelSets "Selection Sets: " items:#("OutterLights","InnerLights") pos: width:120 height:10
 button btnSetMtl "Make Material" width:120 height:20 pos:
