Data is showing proper in app.

so where the error is coming

After removing show data block app don’t give any error.

because select list item block is in Show_Data function

One of the select list item blocks is using index ‘1’ for a list that is empty. Work through your code and use the do it (right click blocks) method to triangulate which one it is.

For example don’t call the show data procedure after the firebase block and then use do it on each list you are selecting from to see which is empty.

add this block

list length -1

It’s working but some data is not coming.

try doing + 1

After +1 not working.

then - 1 is correct maybe your database does not have the values??


wait for someone to help i am really confused :roll_eyes:

wait a minute. I know where your mistake is

add another block for dynamic label

Your blocks in another language that i can’t understand. Please show in english.

it is not necessary! do as i showed
