[jQuery] ui.mouse is null or not an object

[AzamSharp]

Hi,

I am adding the following library and still getting the "ui.mouse is
null or not an object" JavaScript error:

Here are my references:

    <script src="Scripts/jquery-1.2.6.js" type="text/javascript"></
script>
    <script src="Scripts/ui.sortable.js" type="text/javascript"></
script>
    <script src="Scripts/ui.core.js" type="text/javascript"></script>

Thanks,
Azam
