Help with filter to show images

Hi! im trying to make a filter where users can “input a text” and it show certain images. I created a CMS where I have two custom fields, the first one a “text needed to input” and the second one the image related to that input.

I don’t know how to make the connection between the form and the content shown any help is much appreciated!

Here is my public share link: LINK
