Greasemonkeyed Postbank Girotel Zakelijk

I've got fed up with the online banking client for buisiness customers of Postbank. I'm working with more persons on this account, with different bank accounts. I only use one of them, but the website always assumes an other account as default (and an error is quick made with selecting the which account to transfer from). Therefor, I builded a greasemonkey script for firefox to select my prefered account.

Just edit the voorkeurNummer variable.

var selBox = document.getElementsByName('selRekNummer').item(0);
var voorkeurNummer = '123456';

if (selBox.hasChildNodes())
// So, first we check if the object is not empty,
//   if the object has child nodes
{
var children = selBox.childNodes;

//run only if selBox has no onChange attribute
if ((selBox.getAttribute('onChange') == null ))
{
  for (var i = 0; i < chilatt =" children[i].attributes;" tagname ="=" j =" 0;" name ="=" value ="=" selectedindex =" i">
