drop down list problems

Hi all,

I have problem with this combo box or drop down list using javascript in php. I found that it cant select the first option's value (there are value=0, value=1, value=2 but it doesn't work with the 1st option.) Can someone tell me where to correct it's value so that it can select the 1st option too.
Thank you.

function jumpMenu(target,selObj,restore){ 
  if (selObj.selectedIndex>0 && selObj.options[selObj.selectedIndex].value != ''){
    window.open(selObj.options[selObj.selectedIndex].value,target);}
  else if(selObj.options[selObj.selectedIndex].value == '')  {selObj.selectedIndex=0;}
  if (restore) selObj.selectedIndex=0;
}

.....
<tr class="content"><!--<form method="post" name="form2" action="what_on1.php"> -->
                <td width="18%"><select name="select3" id="s3" onChange="javascript:jumpMenu('_top',this,0);">
                  <option value="what_on1.php?pid=0" <? if($_GET['pid']==0) {?>selected<? } ?>>10 per page</option>
                  <option value="what_on1.php?pid=1" <? if($_GET['pid']==1) {?>selected<? } ?>>20 per page</option>
                  <option value="what_on1.php?pid=2" <? if($_GET['pid']==2) {?>selected<? } ?>>30 per page</option>
                </select></td>

I think you need a "starting" option.

<select name="select3" id="s3" [B]onchange="jumpMenu('_top',this,0)"[/B]>
   [B]  <option value=""> Make a Selection </option>[/B]
     <option value="what_on1.php?pid=0" <? if($_GET['pid']==0) {?>selected<? } ?>>10 per page</option>
     <option value="what_on1.php?pid=1" <? if($_GET['pid']==1) {?>selected<? } ?>>20 per page</option>
     <option value="what_on1.php?pid=2" <? if($_GET['pid']==2) {?>selected<? } ?>>30 per page</option>
</select>

Is there any way to make it without starting option? Let's say the pid=0 is the "starting" option where it can be selected and functioned as well? It's ok, I just wanna know only...If there is no other way, I'll follow your advice.

Thank You very much..

 

Drop down boxes automatically display the first option unless another option is selected <option vale='....' selected>.
Have you tried leaving out the php code in the first option - you don't need it.
so it should look like:
<option value="what_on1.php?pid=0">10 per page</option>

I think this should do it.
