Copy value of drop down meny to text field on change

I have an ASP/VBScript page. Using classic ASP, dreamweaver and ms sql 2008

In the ASP I have a drop down menu named 'PetNameSel'. When I make a selection at any given time I need for it to copy the value selected to a text field in the same form. the text field to where it should copy the value is named 'PetName'.

I guess I need a javascript and an 'onchange' action on the drop down ?   Help with both is appreciated.

I added this to the drop down menu:

<select name="PetNameSel" class="bodytext" id="PetNameSel" onchange='ex(this.value)'>

And this is the code I added to the page:

<script language="javascript">
function ex(val)
{
document.getElementById("'PetName").value=val;
}
</script>


But nothing happened when I made my selection.  What am I missing ?
