I am trying to add a Case Team Role, but cannot find it in my trailheard org.

any ideas?

Create a page which displays a subset of Opportunity fields using apex:outputField components. Bind the Name, Amount, Close Date and Account Name fields to the apex:outputField components.The page must be named 'OppView'.
It must reference the Opportunity standard controller.
It must have an apex:outputField component bound to the Opportunity Name.
It must have an apex:outputField component bound to the Opportunity Amount.
It must have an apex:outputField component bound to the Opportunity Close Date.
It must have an apex:outputField component bound to the Account Name of the Opportunity.

for the above task i am trying with the below ccode and its getting an error. Please suggest me the code to execute.

apex:page Standard Controller = "StandardController"/> 
<apex:pageBlock title= "output details">
    <apex:pageBlockSection>
        <apex:outputField value="{! Oppurtunity.Name }"/>
        <apex:outputField value="{! Oppurtunity.Amount }"/>
