Hello Experts,

I am writing a VF Page (Tabbed) and I am working with Service Contracts. I have a related list for a related Service Contract on the Service Contract. Different records types of course. I keep getting the error: 'ServiceContract' is not a valid child relationship name for entity Service Contract. Here is the coding:

<apex:page standardController="ServiceContract" showHeader="true" 
        tabStyle="servicecontract" >
<center>
        <apex:outputPanel style="background-color:red;width:100%;padding:20px;" 
    rendered="{!ServiceContract.Record_Type_Name__c=='Client Contract'}">
    <style>
h1 {
    font-size: 20px;
}
</style> 
        <h1>CLIENT CONTRACT!</h1>
    </apex:outputPanel>
    </center>
    <center>
        <apex:outputPanel style="background-color:red;width:100%;padding:20px;" 
    rendered="{!ServiceContract.Record_Type_Name__c=='Supplier Contract'}">
    <style>
h2 {
    font-size: 20px;
}
</style> 
        <h2>SUPPLIER CONTRACT!</h2>
    </apex:outputPanel>
    </center>
        <style>
      .activeTab {background-color: #236FBD; color:white; 
         background-image:none}
      .inactiveTab { background-color: lightgrey; color:black; 
         background-image:none}
   </style>
   <apex:tabPanel switchType="client" selectedTab="tabdetails" 
                  id="ServiceAccountTabPanel" tabClass="activeTab" 
                  inactiveTabClass="inactiveTab">   
      <apex:tab label="Details" name="ServiceAcctDetails" id="tabdetails">
         <apex:detail relatedList="false" title="true"/>
      </apex:tab>
      <apex:tab label="Approval History" name="ApprovalHistory"
                 id="tabApprovalHist">
          <apex:relatedList subject="{!servicecontract}"
                          list="ProcessSteps" />
      </apex:tab>
            <apex:tab label="Notes and Attachments" name="NotesAndAttachments"
                 id="tabNotesAndAttachments">
          <apex:relatedList subject="{!servicecontract}"
                          list="CombinedAttachments" />
      </apex:tab>
            <apex:tab label="Field History" name="FieldHistory" 
                id="fieldhistory">
<apex:outputLink value="https://cs9.salesforce.com/_ui/common/history/ui/EntityHistoryFilterPage?id={!servicecontract.id}">
click to view field history
    </apex:outputLink>
        </apex:tab>
        <apex:tab label="Supplier Contracts" name="SupplierContracts"
                 id="tabSupplierContracts">
          <apex:relatedList subject="{!servicecontract}"
                          list="ServiceContract" />
      </apex:tab>
      </apex:tabPanel>
</apex:page>

The related list exists on the page layout and all users have acces to it. Does anyone know the Child Relationship name for Service Contracts? Any assistance would be greatly apperciated, thank-you.
