I've created a data collection for my Projects and a Dynamic Item page. I've also created a Dynamic Category page which people can access via buttons on my home page.
When I click on an item on the Dynamic Category page, I"m taken to my Dynamic Item page as expected. Visitors can also see all the projects on a Projects page, where I've added a Grid galllery to display all items in the data collection. Again, clicking on an item there takes me to the Dynamic Item page as expected.
I'd like to add Next and Previous buttons to the Dynamic Item page so people can move through items within that category, or if they've drilled down from the projects page the next item in the whole collection.
I've followed the instructions in the support video on adding a button to the page and linking to the button to the Projects datacollection, but when I preview or publish the site, the button is grey and isn't clickable.
Is the fact that visitors can navigate from either the whole data collection or a dataset causing the issue, or is there something else I've missed?
