Hii,

You can use the jsp variables in javascript..

String somestring  = "whatisthis";

say for ex: alert(<%= somestring%>)

I will take a look at ur previous post.
happy working

didn't have time to read all these, how big your table are? hundred rows, thousand rows, million rows?

>> <% int rowcount = 1; %>
>> Can I use it in my javascript ?
not directly, but you can do this to assign it to javascript var:

<script>
myJSvar = <%=rowcount%>
</sript>

at the minute my table is about 10 rows, its only likely to change + or - 2 every month. I want to apply this to other tables in the future, which will hold up to 50 rows of information, changing + or - 10 every month.

Thanks
John

String[] qty =  request.getParameterValues("qty");
String[] unit = request.getParameterValues("unit");

String[] offerprice = request.getParameterValues("offerprice");
String[] chkbox = request.getParameterValues("chkbox");

boolean doDelete = "Delete Selected Item".equals( action );
boolean[] isChecked = null;

if( itemname != null ) isChecked = new boolean[ itemname.length ];
if( doDelete && chkbox != null ) {
 for( int jj = 0; jj<chkbox.length; jj ++ ) {
      int index = Integer.parseInt( chkbox[jj] );
      // out.println( "got " + index );
      isChecked[index] = true;
 }
}

if (action==null) action="";
