hello @renee.small,
i think i remember answering this question a while back (it seems more than once actually) but can’t seem to find the original topic but I’ll update the thread if i do find it topic, your students projects libraries are calling on datasets that don’t exist in the project their importing it to this means they have to import the dataset on the main project in order for those call functions, in addition to that it also references id tag calls to UI element which may also not exist in the new project that was created, it’s better off being passed as an argument if you have ran through these already feel free to give me a project with one of the libraries implemented with the dataset so i can further debug
