Runtime error. The operation add items to list cannot accept the arguments *empty-string*

Im kinda new to MIT and not really an expert when it comes to TinyDB or lists

So i made an app that's like an shoe store and whenever i press the "add to cart" button, it adds items on the list and on my TinyDB. For some reason when i press the add to cart button, it gives me this error :

This is my blocks.

Where should i look to fix this error? Any help would be great thanks!

an empty text block is not an empty list
use a create empty list block there...



Yay that helped me alot. Thankyouuu so much! :heart:
