Modal image/lightbox not working; full image loads in new page

We are using the infinity scroll at http://coastmetalsolutions.com/new/gallery.html

Please check the top-left thumb titled "Test Title," with the + icon.

When you click the plus icon, instead of loading the full-size image as a modal dialog per lightbox, the full image loads in a new page.

The code seems alright:

	
		
![attachment](images/portfolio/4/1.jpg)

		
			
				Test Title
			
			[](images/portfolio/full/1.jpg)
		
	

Let me know if you have an idea why this modal image isn't working.

Thanks in advance,
Paul

It's because I forgot to link magnific-popup.css at the top. :)
