List viewer is not showing the list

Hi All,

can any one help me to know why this block is not working

i have a key Topic in firebase. and same login is working on other page.

“List_Viewer4 get text items” returns the list that is already there.
What you need to put there is set.

Actually, you need to get the property of each “j”, put that in a temporary list, and after the for each loop, take that list and use it to set the text items of List_Viewer4.
