contact list pagination from trailhead not working
Hi, I am following the List controller trailhead, but the progress bar doesnt work the way it is supposed to. I reduced the no. of records pp to 5 and it still didnt activate the buttons nor page # - I followed the trail step by step; what could I be missing ? Thanks !

Code:
<apex:page standardController="Contact" recordSetVar="contacts">
<apex:form >
<apex:pageBlock title="Contacts List" id="contacts_list">
Filter:
<apex:selectList value="{! filterId }" size="1">
<apex:selectOptions value="{! listViewOptions }"/>
<apex:actionSupport event="onchange" reRender="contacts_list"/>
</apex:selectList>
<!-- Contacts List -->
<apex:pageBlockTable value="{! contacts }" var="ct">
<apex:column value="{! ct.FirstName }"/>
<apex:column value="{! ct.LastName }"/>
<apex:column value="{! ct.Email }"/>
<apex:column value="{! ct.Account.Name }"/>
</apex:pageBlockTable>
</apex:pageBlock>
<!-- Pagination -->
<table style="width: 100%"><tr>
<td>
Page: <apex:outputText value=" {!PageNumber} of {! CEILING(ResultSize / PageSize) }"/> </td>
<td align="center">
<!-- Previous page -->
<!-- active -->
<apex:commandLink action="{! Previous }" value="« Previous"
rendered="{! HasPrevious }"/>
<!-- inactive (no earlier pages) -->
<apex:outputText style="color: #ccc;" value="« Previous"
rendered="{! NOT(HasPrevious) }"/>
<!-- Next page -->
<!-- active -->
<apex:commandLink action="{! Next }" value="Next »"
rendered="{! HasNext }"/>
<!-- inactive (no more pages) -->
<apex:outputText style="color: #ccc;" value="Next »"
rendered="{! NOT(HasNext) }"/> </td>
<td align="right">
Records per page:
<apex:selectList value="{! PageSize }" size="1">
<apex:selectOption itemValue="5" itemLabel="5"/>
<apex:selectOption itemValue="20" itemLabel="20"/>
<apex:actionSupport event="onchange" reRender="contacts_list"/>
</apex:selectList>
</td>
</tr></table>
