Need help linking to slide


A client asked me to create a slider containing 3 of his services. I set it all up but I can’t figure out how to get the link blocks on the left (desktop only) to link to a specific slide.

I’ve seen posts on the subject but they didn’t help me that much. Anyone that can help me achieve this?
