Hi,
Could you please explain your question a bit more.
As far as I get it this can be due to the version of jquery you are using.
Try this:
<!--[if lt IE 9]>
<script src="jquery-1.9.0.js"></script>
<![endif]-->
<!--[if (gte IE 9) | (!IE)]><!-->
<script src="jquery-2.0.0.js"></script>
<!--<![endif]-->
And please check your version of jquery is supported by IE7 or not.
Regards,
Praneet
