I am getting the following error
What I'm trying to cancel the act of deleting an item from list from my database. I am using a list picker. I do the program it shows me this error.
Here is the code I am using for this.
These are the lists
One of the list pickers, I have set the corresponding list as the element
Here is the after picking block
When I open the list picker and I press cancel (cancel is in the the top left of the screen for the list picker menu) instead of an item in the list, then it gives me the error at the beginning of the post.
Is there a way i can fix this?
