Object doesn't support property or method 'init'

[Mat-Moo]

Using BSMSelect plus the sortable plugin as such:-
$(document).ready(function() {
$('.my_select').bsmSelect({
addItemTarget: 'bottom',
title: 'Select an entry to add',
animate: true,
removeLabel: 'Remove',
highlight: true,
plugins: [
$.bsmSelect.plugins.sortable({ axis : 'y', opacity : 0.5 }, { listSortableClass : 'bsmListSortableCustom' }),
]
});
});
Works fine on IE 9 Firefox etc. but of course my customer is using IE8 which causes this issue. Any ideas how I can resolve this? This is when I have mulitple Selects on the screen with that class :)

Seems to be a stray comma at the end on the plugins array that caused this, can close, sorry :)
