You have a typo:

document.getElementsByName("Count").Value = i;
//                                  ^----Typo!

value is lowercase:

document.getElementsByName("Count")[0].value = i;   
//                                     ^----Fixed!  
//                                 ^-------- return HTML Collection, take first.

Better use id:

document.getElementById("hiddenSection").value = i;

You're using jQuery, so you can use one of the following:

$("#hiddenSection").val(i);
$('input[name="Count"]').val(i);
