Hi Stan,

??
I am not sure what your question is.
If you are talking about arrays, try this:

someArray[0] to get the first element.

If you have a selectbox:

<form name="myForm">
<select name="mySelect">
<option value="testing"> testing
<option value="Hammil"> P.Hammil
<option value="Postgres"> Postgres
</select>
</form>

You can get the first element in the selectbox like this:
firstelement = document.forms["myForm"].mySelect[0];

The value like this:
firstelementvalue = document.forms["myForm"].mySelect[0].value;

And if you want to know which element is chooses, try this:
selInd = document.forms["myForm"].mySelect.selectedIndex;

Good luck,
Regards,

In future, please actually include the question in the body of your post,
even if it's just a copy of the subject[1].

<snip> objSelect = top.document.getElementById(strIdSelect);

When you say list, I assume you mean a SELECT element.

If your list is in a form, like this:

<form ... name="formName">
<select ... name="listName">
...

you can reference the list with JavaScript like so:

document.formName.listName

To select the first item in the list, you can write:

document.formName.listName.selectedIndex = 0;

If your list is not part of a form, you'll need to place an ID on it, like
this:

<select ... id="listId">

and access it thus (I included feature detection):

var listObject = null;
if( document.getElementById ) {
listObject = document.getElementById( 'listId' );
} else if( document.all ) {
listObject = document.all[ 'listId' ];
}
if( listObject ) {
listObject.selectedIndex = 0;
}

Hope that helps,
Mike
