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.
A dataset and a collection are two related but different things. You were correct in thinking you should refer to the dataset, but your image is of the collection name/ID, not the dataset’s element ID.
Click on the little dataset icon on the page in question and it should tell you its name. It’s probably #dataset1.
