I have three page type, 'MainPage' has 5 'PageHolder', each 'PageHolder' has number of 'QuestionPage'
on the MainPage.ss I need to access $link of current child 'PageHolder' $Link, inside the custom control of 'firstQuestion'

<% if Children %>
   <% control Children %>
   
      <% if firstQuestion %>
      <p>
      <h2>$PersonaType</h2><br>
         <% control firstQuestion %>
         
         
         <h4>"$Question"</h4> <br>
         $Enquirer <br><br>
         
         Previous Questions:
         
         
         //I need to access this link
         <a href="$Children.Link">View All</a>
         
            
          <br><br>
         <% end_control %>
         
            <% if secondAndThirdQuestion %>
            <% control secondAndThirdQuestion %>
               <a href="$Link">$Question</a> <br>
               
            <% end_control %>
            <% end_if %>
      </p>
      <br>   
      <hr>
      <br>
      <% end_if %>
   
   <% end_control %>
<% end_if %>

the firstQuestion is inside the 'PageHolder'
public function firstQuestion(){
      return DataObject::get("QuestionPage", "ParentID={$this->ID}", '', '', '0, 1');
   }

I am trying to add another function
public function currentPageHolder(){
      return $this->Link();
      
   }

Could someone please shed some light on this. Thank you.

Thanks for the reply. I can't use $Link, because it will return the firstQuestion page Link, I can't use $top.Link, because not only it break out the firstQuestion control, it also break out the Children control, and return the MainPage Link. I have tried them both before, it won't work. What I am after is the Children's Link.

I have managed to get it by using $Parent.Link, you are right, I don't need to write a custom function. Cheers.
