blank brought click collection contained files individual items link list nested nesting package packages page problem products solve songs

The problem is that one of the items in the package is itself a collection of files, so that when people click on the link, they get a blank page, instead of being brought to the list of songs contained in the section.

Is it not possible to have "nested" packages like this? I assume that to solve the problem, we should just link to the individual songs rather than the collection.

No, such nesting is not possible. You should only include products in the package which have individual files.
