Fixing Carousel/Modal images coming from JSON and Javascript

I am Junior Front end Developer the Project is 80% done but I have a little task for you to fix which I can't spend any more time on it. Your task 1. Fix the Preview anchor button, at the moment It's not opening the modal. 2. Sliding images should be displayed only when I click the Preview button also should be specific to the project attached to it. 3. The Slides should have both the image and Text contents 4. Modal and Carousel already Implemented, Your task is to properly fetch the images and text content and display them nicely
