Visualforce page lookup field back to standard object

I have a visualforce page using a standard account object. I also have a child custom object Bids_Sent__c. There is an account lookup field on the related child object titled "Awarded__c".   In my visualforce page i want to some how reference a field Service_Agreement_Verbiage__c on the Bids_Sent__c object. The child relationship name for Bids_Sent__c lookup field "Awarded__c" is "Bids_Sent4". Below I tried this mapping on my VF page and I get the following error.
Error: Unknown property 'VisualforceArrayList.Service_Agreement_Verbiage__c'

{!Account.Bids_Sent4__r.Service_Agreement_Verbiage__c}

Hi Bob,

Please refer below code :

<apex:page standardController="account" recordSetVar="accounts" tabstyle="account" sidebar="false">
<apex:pageBlock >
<apex:form >
<apex:dataList value="{!accounts}" var="a">
<apex:pageblocksection title="Contacts for account {!a.name}" >
<apex:repeat value="{!a.contacts}" var="c">
<apex:inputField label="Contact name" value="{!c.name}"/><br/>
</apex:repeat></apex:pageblocksection> </apex:dataList>
</apex:form>
</apex:pageBlock>
</apex:page>

Thanks

Hi Bob,

Use below Code instead of using "{!Account.Bids_Sent4__r.Service_Agreement_Verbiage__c}" in your VF as "Account.Bids_Sent4__r" is Array/List:

 <apex:repeat value="{!Account.Bids_Sent4__r}" var="bids">
   {!bids.Service_Agreement_Verbiage__c}
</apex:repeat>

Hi Amarpreet,

I don't want to use a repeater, I just want it to show up once on the VF page

Hi Bob,

"{!Account.Bids_Sent4__r}" will always return a Collection (Array/List). So, you need to iterate the List to access the elements of that List. After that, you can fetch the value of the field for each element (i.e. record) one by one.

In your case, an Account can have multiple records of "Bids_Sent__c",then how will you decide that which record of "Bids_Sent__c" will be displayed on your VF.

Also, If you want to fetch only first record, then you can use: " {!account.Bids_Sent4__r[0].Service_Agreement_Verbiage__c}" in your VF. For this, you need "extension" of Standard Controller.
