CSV 1T Uploader Problem

Hi everyone,

i am new to bubble and having a hard time dealing with a file upload using a plugin called 1T CSV Uploader.

I want my users to have an upload for csv to upload a list of buildings that only they (or maybe later other users) can access. But when uploading the file nothing happens.

i tried so many things but nothing works.

Anyone so kind to take a look?

Thank you so much!
