Author Page custom field shows wrong content

I have created a custom profile field called “gallery”.
When I call this field on the Author page, it does show what is entered in the field
but it takes it from the logged-on user, my admin profile where it should display the
content of the Author which page is displayed.

This is the PHP code I use:
<?php echo get_the_author_meta(‘gallery’); ?>

I tried this but it does not work:
<?php $AuthorID = $curauth->ID;
echo get_the_author_meta(‘gallery’ . $AuthorID . ‘]’); ?>

Can you tell me what the code should be?
Best regards,

Peter
