That makes sense but I am unsure as to where exactly or how to modify my code to get it to work. I am rather new to this sorry

The bottom of the page should look like this:

<script type="text/javascript">
var selects = document.getElementsByTagName( 'select' );

for( var i = 0, box; ( box = selects[ i ] ); i++ )
  if( box.name.indexOf( 'ereg|' ) == 0 )
    box.onchange();
</script>
</body>
</html>
