Multiple Options in a Pop Up needed to have answer go to textfield

I found this script on the web. It works for having multiple options in a pop up.
 
I would like to have the options I pick to populate a textfield. I have tried everything I know, If any body can help that would be great.
 
Thanks
  
form1.#subform[0].Button11::click - (JavaScript, client)
 
var FormRouting =
{
 
result:"cancel",
DoDialog: function(){return app.execDialog(this);},
bChk2:false,
bChk3:false,
bChk4:false,
bChk5:false,
initialize: function(dialog)
{
var dlgInit =
{
"Chk2": this.bChk2,
"Chk3": this.bChk3,
"Chk4": this.bChk4,
"Chk5": this.bChk5,
};
dialog.load(dlgInit);
},
commit: function(dialog)
{
var oRslt = dialog.store();
this.bChk2 = oRslt["Chk2"];
this.bChk3 = oRslt["Chk3"];
this.bChk4 = oRslt["Chk4"];
this.bChk5 = oRslt["Chk5"];
},
