CMS not linking with lightbox gallery

I cloned a gallery template from another user, but when I try to link the image gallery field from my CMS, it does not populate. Any suggestions? [The "Cloneable Area in Div block 104 is the new lightbox template that I’m trying to make work. The Image 45 and HTML that are hidden are what I currently have that I’m trying to improve on.]

Here is my public share link: [LINK](Webflow - Art Gallery)
