Hi,

Problem:
             I have populated a dropdown box using Javascript, but on the  
aspx.vb page I am not able to access the value of the dropdown item. The 
error is:

Exception Details: System.NullReferenceException: Object reference not set 
to an instance of an object.

And My client Side Code is:

function populate(strData)
            {
               arrData=strData.split(",")
               var sub_combo=document.forms[0].sub_cb

               sub_combo.options.length=0
               for(var i=0;i<arrData.length;i++)
               {
                   var opt=document.createElement("option");
                   opt.value=i;
                   opt.innerHTML=arrData[i];
                   document.forms[0].sub_cb.appendChild(opt);
               }
            }
please help me.
Thanx in advance

Barani
