cut n paste a copy of the returned json string and post it here - firstyou highlight it and apply the pre-ormatted text option on it (see option in gear icon) and post the raw json text here and we will see what approach to take below is an example. ```auto {"type":"bar","data":{"labels":["Q1","Q2","Q3","Q4"],"datasets":[{"label":"sales","data":["91","60","70","100"]},{"label":"profit","data":["78","80","78","90"]}]},"options":{"scales":{"yAxes":{"stacked":true},"xAxes":{"stacked":true}}}} ``` ---

I don’t know if is that you want, but, this my json: ```json { "user_id": { "class": { "lessons": { "class_name": { "student 1": { "time": 0, "answers": "1,2,3,4" }, "student 2": { "time": 0, "answers": "1,2,3,4" }, "student 3": { "time": 0, "answers": "1,2,3,4" }, "student 4": { "time": 0, "answers": "1,2,3,4" } } } } } } ``` ---

like this? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/3/531727b3a7a2d49d354e319a9f34b6698cb08ab6.png) here are the blocks ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/2/92a13fc7d647a2b744588255aa6bb89822603818.png) the outcome is a text so you should run it thru the list\_from\_text block using delimiter “|” to get a list. i also cheated - i already know what names are the various columns so i hardcoded the property values [https://x.thunkable.com/copy/e1ab4a41276e3f8950dcf74ce1c7c8b5](https://x.thunkable.com/copy/e1ab4a41276e3f8950dcf74ce1c7c8b5) It looks like it requires a recursuve solution, which i s difficult for me to arrive at at this time. Maybe someone else may find the recursive answer easily. ---

No, I would like Thunkable show a list viewer of different lessons, next user click, show list of different class, user pick one, and it show a table of different value of each students User\_id it is the identifiant of user by firebase and first “class” key it’s to sey that you need to get these value ---

I’ve given you most of the tools you’ll need. The first item in the list builder block returns the classes for a user\_id. Just put them in a list viewer. After pick an entry, goto a new screen where there’s a new list viewer whose elemenr entriesc are from the 2nd item in my.list builder block, etc. Doi the same process for the remaining levels. Hint. Include the “path” ( eg. User\_id…class…lessons… ) at the top of every screen and append the current elemenr to the new path in the next screen. Note; the path is the string that appears in get\_property block. Good luck! ---
