I have a jquery script that works perfectly fine in all browsers except IE. Part of it works in IE but the main part doesn't and I'm not sure why.

```
$(document).ready(function() {

$(".close").hover(

function() {
    $(this).css({
        opacity: "0.4"
    });
}, function() {
    $(this).css({
        opacity: "0.2"
});
});
$(".name").hover(

function() {
    $(this).css({
        color: "#ED6736"
    });
}, function() {
    $(this).css({
        color: "#292929"
});
});

$("#wrapper_MAIN_INPT").css({
'height': $("#practice_staff_MAIN_INPT").innerHeight()
});

$("#STAFF_HEADER_MAIN_INPT").css({
'marginTop': $("#practice_staff_MAIN_INPT").innerHeight()
});

$("#BIO_MAIN_INPT").css({
'marginTop': $("#practice_staff_MAIN_INPT").height()
});

$("#EDU_MAIN_INPT").css({
'marginTop': $("#practice_staff_MAIN_INPT").height()
});

$("#CONTACT_MAIN_INPT").css({
'marginTop': $("#practice_staff_MAIN_INPT").height()
});

var a1, a2, a3; //Establish Loading Variables 

$(".name_MAIN_INPT").on('click' , function() { 

MAIN_OUTPT_close();
close_850();
FOX_close();
SPEECH_close();

a1=0; //Reset the Loading Variables
a2=0;
a3=0;

var id = $(this).attr('id');

Here is the link to the full page here <http://www.brighamandwomens.org/Patients_Visitors/pcs/rehabilitationservices/mock/about_us/about3.html> the name links that work turn orange when you roll over them and you can see them work in Firefox, Chrome, Safari, but once again not luck in IE. Any help would be great, thanks.
