If yes, open another screen
if you don’t fill in the fields
Error
doesn’t run properly
Somebody…
This is called data validation… in your case before trying to select an item from a list, make sure the list is not empty
Also let me suggest you to switch screens correctly

Could you show something similar?
I don’t understand the meaning.
From closing the screen Ok!
If is list empty get global receber
Then display a nice error message
Else continue with your processing

Dear friend
I understand most of it, but I’m still in the same place,
he follows…
Caption 4 has been completed
As for caption 5 where it is empty, you have to check if it is empty and change the screen, but nothing happens.
any tips?
My result in caption 5 is empty
so you would have to change the screen to fill in the empty field
I just can’t change the screen
When I have a positive result, it’s ok
but negative result error
as you can see yourself, the list does have only 4 items
to select the 5th item will obviously result in an error therefore
how do you store items in the list? because each item is currently a list itself… this actually does not make sense… if you store each item as text (and not as another list) you do not need to remove the brackets as you are doing it currently
learn to work with lists…
