Hola, ¿como hago para que el select list item no seleccione un numero de la lista si no tiene mas datos para colocar?
Explicación: Tengo una base de datos, app inventor llama el column name y las pone en un label y cuando no tiene mas datos para colocar sale "Select list item: Attempt to get item number 3 of a list of length 2"

Hello, how do I make the select list item not select a number from the list if it has no more data to place?
Explanation: I have a database, inventor app calls the column name and puts them in a label and when it has no more data to place it exits "Select list item: Attempt to get item number 3 of a list of length 2"
and since the number is taken from the length of the list, I cannot define the number because it is not a permanent number, since that data changes depending on the table (MySQL) that I choose
Basically it consists of taking the names of the columns of a table from a database and placing them in a label (I have done this) but when changing the table it does not allow to put the column name due to the error "Select list item: Attempt to get item number 3 of a list of length 2".
So far I have 2 tables "usuarios - tabla_usuarios" and table_users if it allows it to be placed since it is 7 while the "users" table does not because it is less than 7 (7 is the maximum label I have)
