Fill Field from check box dialog

I have a js dialog pop which includes 7 check boxes. The pop-up was created with AcroDialog.
 
I need to return a maxium of five values to a field named CLSN_INURY_TYPE.
 
I am using Live Cycle Designer 7. The code is as follows:
 
//Acrobat JavaScript Dialog
//Created by DialogDesigner from WindJack Solutions
var Injury_Type =
{
 
result:"cancel",
DoDialog: function(){return app.execDialog(this);},
b0:false,
b1:false,
b2:false,
b3:false,
b4:false,
b5:false,
b9:false,
initialize: function(dialog)
{
var dlgInit =
{
"0": this.b0,
"1": this.b1,
"2": this.b2,
"3": this.b3,
"4": this.b4,
"5": this.b5,
"9": this.b9,
};
dialog.load(dlgInit);
},
commit: function(dialog)
{
var oRslt = dialog.store();
this.b0 = oRslt["0"];
this.b1 = oRslt["1"];
this.b2 = oRslt["2"];
this.b3 = oRslt["3"];
this.b4 = oRslt["4"];
this.b5 = oRslt["5"];
this.b9 = oRslt["9"];
},
