Microsoft JScript runtime error: 'jQuery' is undefined

In  some cases  as we know the silly internet explorer gives us a weird errors as the tittle of this post, so after searching a lot of time please make sure while you adding the JQuery References class to put it like this (~/).


 <script src="~/Scripts/jquery-ui-1.8.20.custom.min.js" type="text/javascript"></script>
 <script src="~/Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
 <script src="~/Scripts/jquery-1.7.2.js" type="text/javascript"></script> 

Instead of this

 <script src="Scripts/jquery-1.7.2.js" type="text/javascript"></script>

This error may appear or may be not just make sure to prevent any wasting time in the future
