You can use the “url from uploaded file” block in the Files drawer to upload an image to Cloudinary and return the hosted url. Assigning it to a variable makes it accessible to other areas of your code on that screen or other screens.
The green blocks such as “row id” are only valid within the “do” section of a function. So you wouldn’t use that block above where you see it. You generally don’t need to do anything with a “row id” block after creating a row unless you need to reference it later with another block that requires a row id (such as when deleting a row).
