"Total" line not displaying on PageBlockTable - code compiles without error but total is not displayed

Hello, 

I have a pageBlockTable where I am attempting to display and total current outstanding invoices.  Here is the code behind my table, which compiles without error: 

 

<apex:pageBlock title="Invoices This Week">
<apex:variable var="totalBalance" value="{!0}"/>
<apex:pageBlockTable value="{!listOfCO}" var="co">
   <apex:column value="{!co.Buyer_Name__c}"/>
   <apex:column value="{!co.Total_Order__c}"/>
   <apex:column headerValue="Balance to Collect">
      <apex:outputField value="{!co.Balance_to_Collect__c}"/>
      <apex:variable var="totalBalance" value="{!totalBalance+co.Balance_to_Collect__c}"/>
   </apex:column>
</apex:pageBlockTable>
</apex:pageBlock>

but my "Total" variable does not display (see picture below).  What piece am I missing in order to make this show??? Thank you in advance for your help!

    Hey Bob - a quick update... I used the info you gave me at put this together:

     

    <h2>Invoicing</h2>
      <apex:panelGrid width="100%" columns="2" styleClass="paneltop">
    <apex:pageBlock title="Invoices This Week">
    <apex:variable var="totalBalance" value="{!0}"/>
    <apex:variable var="totalOrders" value="{!0}"/>
    <apex:pageBlockTable value="{!listOfCO}" var="co">
       <apex:column value="{!co.Buyer_Name__c}"/>
       <apex:column value="{!co.Total_Order__c}"/>
       <apex:column headerValue="Balance to Collect">
          <apex:outputField value="{!co.Balance_to_Collect__c}"/>
          <apex:variable var="totalBalance" value="{!totalBalance+co.Balance_to_Collect__c}"/>
           <apex:variable var="totalOrders" value="{!totalOrders+co.Total_Order__c}"/>
             </apex:column>
           </apex:pageBlockTable>
          <br></br>   
          <apex:panelGrid columns="2" width="100%">  
       <apex:outputText style="font-weight:800" value="Total Funds Not Yet Collected: ${0, number, 00,000}">
           <apex:param value="{!totalBalance}" />
       </apex:outputText>
        <apex:outputText style="font-weight:800" value="Total Orders Sent this Week: ${0, number, 00,000}">
           <apex:param value="{!totalOrders}" />
       </apex:outputText>
       </apex:panelGrid>

    and it is working great!
