New Post: Get list item count for a week

Here is my altered code after the comments:

<script type="text/javascript" src="/scripts/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="/scripts/jquery.SPServices-2014.01.min.js"></script>
<script language="JavaScript">
$(document).ready()
var itemCount;
  var daysFromSunday = (new Date()).getDay(),
    dateOffset = (
            daysFromSunday > 0 ? " OffsetDays='-" + daysFromSunday + "'" : ""
        ),
        query;
    var daysToSunday = 7 - daysFromSunday;
alert(daysFromSunday);
alert(daysToSunday);
    var query = "<Query>" +
        "<Where>" +
        "<And>" +
        "<Geq>" +
        "<FieldRef Name='CreateDate' />" +
        "<Value Type='DateTime'>" +
        "<Today OffsetDays='-" + daysFromSunday + "'/>" +
       "</Value>" +
        "</Geq>" +
        "<Leq>" +
        "<FieldRef Name='CreateDate' />" +
        "<Value Type='DateTime'>" +
        "<Today OffsetDays='" + daysToSunday + "'/>" +
        "</Value>" +
        "</Leq>" +
        "</And>" +
        "</Where>" +
        "</Query>";
alert(query);

    $().SPServices({
        operation: "GetListItems",
        listName: "Opportunities",
        async: false,
        completefunc: function(xData, Status) {
            itemCount = $(xData.responseXML).SPFilterNode("rs:data").attr("ItemCount");
        }
    });
 alert(itemCount);
</script>

I put the alerts in and get sensible returns for days to and from sunday but on the alert for query it returns the whole code not a value. The last alert then returns the total amount of items in the list.

The list contains about 3 items that have been created since Sunday with a CreateDate field of 26/02/2014
