How to handle an error when page.context.user. does not exist

I'm getting an error on View My Profile page, which is likely coming from this code: <#if user.id == page.context.user.id>

 

My guess is that page.context.user.id or user.id doesn't exist, so it throws an error. How do I handle that error in a conditional, so that instead of breaking, it just returns false, such as:

 

     <#if user.id?? && page.context.user.id??>
         <#if user.id == page.context.user.id> <#-- Only show Kudos tab on your own profile page -->
           //stuff here
         </#if>
     </#if>

 

Thanks! Here's the whole code:

 

<#-- Add links -->
<ul class="profile-tabs">

   <li class="tab-activity">
      <a href="/t5/user/viewprofilepage/user-id/${page.context.user.id}/tab/activity">${text.format('general.Posts')}</a>
   </li>
     <#if user.id?? && page.context.user.id??>
         <#if user.id == page.context.user.id> <#-- Only show Kudos tab on your own profile page -->
           <li class="tab-votes">
              <a href="/t5/kudos/mobilemykudospage">${text.format('text.UserRankNodeEditor.kudos.title')}</a>
           </li>
         </#if>
     </#if>
   <li class="tab-bio">
      <a href="/t5/user/viewprofilepage/user-id/${page.context.user.id}/tab/bio">${text.format('taplet.commonComponents.nodeDescription.title')}</a>
   </li>

</ul>

    Can you try:
    page.context.user?? && page.context.user.id??

      Perfect! That worked, thanks. The main issue was that when you're on the mobilemykudospage, any use of page.context.user.id throws an error. The below code (included below), avoids that.
