Problem with FireBaseDB.Get Tag List

Dear all,
Please help me this problem,
blocks (1)
blocks (2)
blocks (3)

When I clicked Button2 then Label_Noi_dung.Text got value equal global so_luong instead of Label_Noi_dung.Text got value equal “Danh_sach_ma_app”.

Thanks in advance for your help!

Do you have tags under that bucket name? Please post a screenshot.

Thank for replying,

Blocks,

blocks (1)
blocks (5)
blocks (6)

FirebaseDB,
FirebaseDB

Result, when I clicked Retrieve button

Label_Status.Text got value equal 0 instead of equal 5. You can fix this error for me.

Thank you again,
Best Regard,

Ya because your blocks are wrong…

Thank you,
If I remove block (set global so_luong to 0) then Label_Status.Text got still value equal 0 instead of equal 5. You can fix this error for me.
Thank you again,
Best Regard,
