perch_content_custom Not Displaying

Hi

I've coded 100's of perch_content_custom but for some reason cannot for the life of me get this one to work.

I have a region on the home page called Success Stories.

I want to bring that content onto another page so have...

 perch_content_custom('Success Stories', [
        'page'=>'/index.php',
        'template'=>'success_stories_banner.html',
        'sort'=>'success_stories_user_name',
        'sort-order'=>'RAND',
        'count'=>1
    ]);

...The perch_custom_content isn't outputting anything from the success_stories_banner.html template, nor are there any errors?

Any pointers would be much appreciated.
