Button Link do not work

I am using the Photo stack from Nick Cates. To start a gallery view, I have to use this syntax in the link:
As you see, there is no URL, but just a name and a value. This works with any text or image, but the button and other stacks of foundry can not work with this link type. Can you please check this, as I need it for a customer to work?

Perhaps I need to adjust the URL, but it works per description with any image/text link I set up so far.

Thank you

Good morning @huavancuong0404

We’ll need an example of the type of link you’re trying to use in the Button stack. Without that we’d all just be guessing at what you might be dealing with.
