Hi @Pyromania666
Can you please post a snippet of your code which is used to make the gallery?
Am I right in assuming this piece of code is within a loop which is rendering many posts on 1 page?
There should be no need for a ‘unique ID’ for each gallery, the get_field function can load from multiple posts on 1 page. Perhaps the $post object is not correctly setup in your loop?
Thanks
