Problem in merging java script and java code

Question

hi,
i want to merge java and javascript code but it is giving some surprising results.
this is my code:
<script language = "javascript">
<%
String query_result= "1";
String buttontype="";
buttontype=(String)session.getAttribute("buttontype");
query_result = (String) session.getAttribute("query_result");
out.println(query_result);
if(buttontype!=null&&(buttontype.equals("submit")))
out.println(buttontype);
%>
alert(<%=ka%>)
</script>
<%
%>
now if i'll move "<script language = "javascript">" to:
<%
String query_result= "1";
String buttontype="";
buttontype=(String)session.getAttribute("buttontype");
query_result = (String) session.getAttribute("query_result");
out.println(query_result);*/
if(buttontype!=null&&(buttontype.equals("submit")))
out.println(buttontype);
%>
<script language = "javascript">
alert(<%=query_result%>)
</script>
<%
%>
then it prints correctly and gives alert "1" but if i'll change query_result="manish" then it is not giving alert also
i don't know wht is happening
plz help me out

hi pgeuen,
Thanx for ur reply
now its working i have changed my jsp exp. tag to
alert("\"<%=ka%>\"")
and it is displaying correctly.
and if i'll give the scripting tags in "if block"then it will work but till now i didn't get why i was not getting any output when the scripting tags covers the whole jsp code. i think we can mix java script and jsp in any way.
well thanx a lot.
