IF( MONTH( NOW() ) = 12,
  DATE( YEAR( NOW() ), 12, 31 ),
  DATE( YEAR( NOW() ), MONTH( NOW() ) + 1, 1) - 1

I'm getting the error "The outputLink component is not binding to the ID of a case" for this challenge. I've checked several threads on here and I'm almost certain it should be correct. It does link to the details page for the case. 

I initially just had the ID linking but have changed it so both case number and id link via id in case that mattered. 

I've also previously tried having a complete url as the value but no luck. 

Any help would be appreciated.

<apex:page controller="NewCaseListController">
 
        <apex:pageBlock title="New Case List" id="cases_list">
            
    <apex:repeat value="{! newcases }" var="cases">
       
        <apex:outputLink value="/{! cases.id}">
        ID:  {! cases.id }
        </apex:outputLink><br/>
        <apex:outputLink value="/{! cases.id}">
        Case Number:  {! cases.CaseNumber }
        </apex:outputLink><br/>    
    
    </apex:repeat>
            
        </apex:pageBlock>

I have been able to get similar ones to work (based on prior challenges) but I am struggling here.  Probably a newbie mistake somewhere.  Any help would be appreciated!  Thanks, Aron
