Hello good day. I stopped working with the app inventor. I am now working with thunkable. Now I have a question. working on firebase. When I press the button, I add a school. I want to get teachers and students under this section.

I think this is okay. Would you recommend another method?

Slightly better (or at least simpler) might be to use [Cloud variables](https://docs.thunkable.com/variables#app-stored-and-cloud-variables), which use Firebase, so you could use something like:

![Screen Shot 2019-12-12 at 1.45.05 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/a/da77b7633b1ae0dbcdb3344afaa4ffb1cd7da528.png)

The full `'create object'` would be the same as in your `'Realime_DB1 call Save'` example.

Hope this helps.

I want a structure like the following on the firebase. but I can’t use a variable with create object. I’d appreciate it if you helped. Thank you

**school name 1**  
**Teachers**  
teacher no 1

- name  
-age  
…

teacher no 2  
-name  
-age  
…

**students**  
students number 1  
-name  
-age  
…  
student number 2  
-name  
-age  
…

**school name 2**  
**Teachers**  
teacher no 1

- name  
-age  
…

teacher number 2  
-name  
-age  
…

**students**  
student # 1  
-name  
-age  
…  
student number 2  
-name  
-age  
…

Hi,

One of the options

},  
{  
“name”: “”,  
“age”: “”  
}  
],  
“students”: [  
{  
“name”: “”,  
“age”: “”  
},  
{  
“name”: “”,  
“age”: “”  
}  
]  
},  
{  
“name”: “”,  
“teachers”: [  
{  
“name”: “”,  
“age”: “”  
},  
{  
“name”: “”,  
“age”: “”  
}  
],  
“students”: [

“age”: “”  
},  
{  
“name”: “”,  
“age”: “”  
}

I would like to add the teacher numbers with the variable at the bottom of the example.

I showed you an example. You can add as many fields to it as you need.

Can you explain in some more detail why you say that you can’t use a variable with create object?
