New Post: Get list item count for a week

You're missing something in the code above, right around here:

<script language="JavaScript">
{   var itemCount;

What's this extra '{'? My assumption, given that the code block ends with '});' is that this should really be:

<script language="JavaScript">
$(function() {   var itemCount;

If that does not work, then you need to put in a few alert()'s along the way to test for expected flow of the piece of code.
Also,
Sorry to ask the obvious: you do have item in the list whose "CreateDate' is within the last 4 days, correct?
