problem in retriving multiple checkbox values

[sahana mithra]

Hi all,
I am unable to access the values of checkboxes i select.
Here is my code which i tried.

<input type="checkbox" id="<%= "gname_" + in.intValue() %>" name="chkBox" onclick='chkboxSelect(localArrGroupNames[<%=in.intValue() %>],<%= "gname_" + in.intValue() %>)'>

JS code:
function chkboxSelect( chkBoxValue, id, value){
      var i=0;
    if(id.checked)  {
       var selected;
       alert("id:  " + chkBoxValue + i);
       selected[i] = chkBoxValue;
       i++;
    }

    }

I get only one value in my alert though I select more than one value.
For example if i select red, blue, green, After I select each, I get only one in my alert.
Please help me . Thanks in advance.
