How to get multiple tags data from firebase?

See example below - just replace Your_Project_Bucket with yours [image] [image]

Hello there,
I didn’t find any topic related to my logic or problem, that’s why I created.
Shared topic has only one value stored in a tag but in my DB I stored more than 2 values in a tag.
So, if you are able to help please let me know.

Someone should make a tutorial on how to search the community
Friend, use logical reasoning…
Ask yourself: in what format do I save the Tag data?
and then you will know how to handle the GET return.

Apparently you haven’t tried anything yet

@RAVAN_0001

everytime error occurs.

post your error and blocks you tried along with your query

[RAVAN_0001 (Deepanshu)]

set the project bucket

Got all tag successfully
In Label4 I stored length of the list.

For testing I store all tags in a list

Getting all tag values

Now I got all the values and tags successfully and I store the values in a list

The result is this

Now In procedure3 I want to store values separately in multiple labels. For example I have 3 details (0001,19-08-23,exit) I want to use there three value separately. I tried to store data in list view but data duplicate issue occur. what I tried recently

“Select list item: Attempt to get item number 2 of a list of length 1”

Blocks

I don’t why this error occurred.
“Attempt to invoke virtual method ‘java.lang.Class java.lang.Object.getClass()’ on a null object reference”

If you want, send me the aia file and I’ll fix it.

[RAVAN_0001 (Deepanshu)]

okay

test.aia (7.3 KB)

there is total two error
first- “Select list item: Attempt to get item number 2 of a list of length 1”

second- “Attempt to invoke virtual method ‘java.lang.Class java.lang.Object.getClass()’ on a null object reference”

[Gaston (zodiaclogic)]

for each GET VALUE, a GOT VALUE is executed.
the problem is that the indicated blocks are executed repeatedly before getting all the data, for example “Procedure3”

Note that if you remove what is indicated and then execute it manually or from a button, there is no error

Thank you! @Gaston
I am marking your reply as solution as logic is working fine.
Thank you once again.
