    I am trying to write a javascript code.  This is code I have right now.

    <script type='text/javascript'>
    function onCheckBoxClickctl00_Content_ddc1_CB1(){
    var combo=$find('ctl00_Content_ddc1_CB1');
     var CountChecked=0;
    var text='This is the text message';
    var max ='4';
    var items = combo.get_items();
    for(var i=0;i<items.get_count();i++){
    var item=items.getItem(i);
    var chk1=$get(combo.get_id()+'_i'+i+'_chk1');
    CountChecked ++;
    if(max < CountChecked) {
    chk1.checked = false;
     if(CountChecked > 3)
    { text = 'You have ' + CountChecked  + ' items selected :';}


    I would like to write the text in the first line of the drop down.  Something like items._array[0].set_text(text).  But when I did this I get an error.  Can you please tell me how to do this.

    Thank you
