I'm trying to fetch the custom objects record details and display on the VF page with below code.

In my case, I have case lookup with a custom object (say, Evaluation__c) and my requirement is - open a case on a VF page and display details of Evaluation__c object record below.

Am I missing something? Pls guide.

Image illustration below:

Code below:

<apex:page standardController="Evaluation__c"> apex:form apex:pageBlock <apex:pageBlockSection title="Evaluation Details" columns="2">

            <apex:pageBlockSectionItem>
                <apex:outputLabel value="Case Number" />
                <apex:inputField value="{!Evaluation__c.Case__c} " id="Case__c" label="Case Number" required="false" />
            </apex:pageBlockSectionItem>


        </apex:pageBlockSection>
        <apex:pageBlockButtons>
            <apex:commandButton value="Submit" action="{!save}" />
        </apex:pageBlockButtons>
    </apex:pageBlock>

    <apex:pageBlock>

        <apex:pageBlockSection>
            <apex:pageBlockTable value="{! Evaluation__c }" var="e">
                <apex:column value="{! e.Case__c }" />
                <apex:column value="{! e.EvaluationNumber__c }" />
                <apex:column value="{! e.Max_Points__c }" />
                <apex:column value="{! e.Score__c }" />
            </apex:pageBlockTable>
        </apex:pageBlockSection>

    </apex:pageBlock>

</apex:form>

</apex:page>
