How to create a new thing multiple times on the same list with different dates input from air date picker?

Hi Bubble community.

First, a big thank you to all the contributors and for
I have no programming knowledge and discovered Bubble a few weeks ago (my first no code adventure).
Mind-blowing. I have learned so much from the forum already.

Cannot find what am I doing wrong in this one.
I am trying to create a few identical entries (“create a new thing”) in one click of a button with the only difference is the date (Air - date picker - multiple date selection).
I have attached a few screenshots.

Many thanks in advance
