I tried to follow the instructions to code Previous/Next buttons for my website, but I keep getting a "No01-SENS is not a valid selector name" message. I'm positive it is the ID of my dataset, so I don't understand what I'm doing wrong. I've spent the last twenty minutes looking for an anwser online, but so far, no luck.
Here's my URL : https://www.revueperceptions.com/numero01
Thanks in advance!
