Fix slider to make images clickable and link to page

Hello I am looking for someone to help me fix something in the slider on my website. I want the images that rotate on the slider to link to a page in my website, but for some reason this wp theme doesn't allow this. Ahavamedical.com. Please do not contact the business. _Contact me directly_. I would also need instruction on how to make these changes do that in the future if I want to ad new images to the slider and link them to something else it would work. Thank you
