Let me explain you how my site is working before asking the question :
1. The "album1" database
Here it how it looks. On the screenshot, you can see 3 albums, and each line corresponds to a photo, and the dynamic page compiles every page with the same "title_link" and puts the photos together to make a galery.
Here is one exemple of a dynamic page created by this database : https://www.vudecypres.com/album/20-mille-lieues-sous-l-hiver
2. The "albums" database
This database is for the page https://www.vudecypres.com/beta-albums . It presents all the albums on the site together. The "link" column is in red because it doesn't recognize the text as an url even if it is one, directing to my own site (but if I put here the full url, it opens the album into a new tab and I don't want that behaviour to happen).
3. The feature I would develop :
On the dynamic page of the "album1" database, (as https://www.vudecypres.com/album/20-mille-lieues-sous-l-hiver ) I would like to put buttons linking to the next album (in the order of the column "key").
Here are the buttons :
I tried this settings :
I honestly don't know what is missing.
Can anybody help me ?
Have a great day !
