<script type="text/javascript">
jQuery(document).ready( function(){
	jQuery( '.mainmenuselect' ).change(function() { 
		window.location = jQuery(this).find( 'option:selected' ).val(); 
	}); 
});
</script>

<!-- Add this line of code after line 8 -->

	jQuery( '.mainmenuselect' ).find( 'option[value="' + window.location.href + '"]' ).prop('selected', true);
	
<!-- You should end up with this code: -->

<script type="text/javascript">
jQuery(document).ready( function(){
	jQuery( '.mainmenuselect' ).find( 'option[value="' + window.location.href + '"]' ).prop('selected', true);
	jQuery( '.mainmenuselect' ).change(function() {
