I am trying to rollup data from our customer object (account_territory__c) to the account object.  Basically, I the question to answer is: "what are all the account_territory__c under a global account"?

My challenge is that the account_territory__c is related to the account object on a lower level of the account hierarchy("ean level"-individual accounts).  This allows different teams to be created for different accounts.

my visual force page works on the individual account object where the account_territory__c directly relates, but not when i test on the global account record type:

<apex:page standardController="Account">
    <apex:detail />
    <apex:pageBlock title="Territory Team">
        <apex:pageBlockSection title="Entity team">
        <apex:pageBlockTable value="{! account.Territory_Team__r}" var="item">
            <apex:column value="{!item.name}"/>
            <apex:column value="{!item.Primary_Team_Member__c}"/>
        </apex:pageBlockTable>
        </apex:pageBlockSection>
    </apex:pageBlock>

I have had success querying in the developer console for the right data with the soql query below:
SELECT Name, Primary_Coverage__c, MAX(Primary_Team_Member__c), Segment_Name__c, Region_Indicator__c, Align_Type__c, Sales_Org_Name__c, Sales_Group_Name__c, Region_Name__c
FROM Account_Territory__c
where
Entity__c ='001E00000073SBYIA2'
GROUP BY Name, Primary_Coverage__c, Segment_Name__c, Region_Indicator__c, Align_Type__c, Sales_Org_Name__c, Sales_Group_Name__c, Region_Name__c


I dont know how to connect the two.  Please help!!

Thank you!
