Problem in dropdown with db

<script>

function filldroplist1(){

// this function is used to fill the droplist1 list on load

addOption(document.formname.droplist1,"1","Glazing","");

addOption(document.formname.droplist1,"2","Cladding","");

addOption(document.formname.droplist1,"3","Louver","");

}

function Selectdroplist2(){

// ON selection of droplist1 this function will work

removeAllOptions(document.formname.droplist2);

addOption(document.formname.droplist2,"","droplist2","");

document.formname.action="samepage.jsp?value1="+document.formname.droplist1.value;

document.formname.submit();

document.write(value1)

<%

String prod = (String)request.getParameter("value1") !=null ? (String)request.getParameter("value1") :"none";

out.println("droplist1" +prod);%>

if(document.formname.droplist1.value !='none'){

<%//here getting values from database %>

//adding with drop down here

addOption(document.formname.droplist2,"","<%= product_sub%>");

} %>}}

Here while choosing drop list1 it gets datas from db to drop list2..

My problem is , i can get the values from db but not able to add it to the drop list2?

Could anybody tell me?What is wrong with it?

Suggestions greatly appreciated..
