I have this js code:

var id = document.getElementById("myDiv").getAttribute("data-id");  

et="Your Message Here";
el="http://x2.xclicks.net/sc/out.php?s="+id+""
sl=new Array(); 
sn=new Array();
a="</a>"; af="<a target='_blank'";


function dw(n) {document.write(n,"\n");}
function showLink(n,s,b){
    if(!s) {s='anc'} 
    if(!b) {b=''} 
    else   {b="&b="+b}
    ast = af+" class='"+s+"' href='"+el; 
    n   = n-1; 
    if(sl[n]&&sl[n]!="") {
        dw(ast+"&o="+sl[n]+b+"'>"+sn[n]+a)
    } else {
        dw(ast+b+"'>"+et+a)
    }
}

Which I load in my header.php like this:

<script type="text/javascript" src="<? bloginfo('template_url'); ?>/js/trf.js"></script>

The problem is that although this is correct:

var id = document.getElementById("myDiv").getAttribute("data-id");

I get this error:

getElementById() is null or not an object

Ady Ideas why?

Do I need to declare a document ready or something?

    Do I need to declare a document ready or something?

    Yes, exactly. Before the document is ready (ie all tags are parsed to DOM elements), you won’t be able to get elements by id. This would only work for elements above your script tag, which are already parsed. Moving the script inclusion from <head> before the end of </body> would help. Alternatively you’ll need to use one of the various DOMContentLoaded or onload events, which unfortunately are not cross-browser supported. I recommend to search for a good snippet or use a library.
