The block “append” works only if you already have a list in your firebase . Why you haven’t any value ? You have to create a record ? How you want to save data?
You have to read something more about firebase block and how they work
Hi , mark as solved in the right message.
To move from visible arrangement to unvisible is very easy , just use the set visible to true or false with the arrangment blocks. You can set it with a button or a clock or as you want according to your project.
You have to use two of them together ,one to set visible and one to hide the 2 arrangment
