Since the project page is not live, it’s difficult to tell all the details for sure, but here’s what I gather from your screenshots:
- The base project is set as $4.00, is there any file that does not have a manual price? If not, people that purchase your base project will have access to no files.
- You have 4 files, that start from $5.00 and up. Files that you set the price manually work in a tier system. That means if someone spends $20.00 on your project, they will have access to all files priced $20.00 or lower. In your case, if someone spends $30.00, they will be able to download all files associated with that project.
If I’ve understood you correctly, I’d suggest to mark the price of the base project as $5.00, and uncheck the manual pricing of the Basic package.
Hope that makes sense :)
