I see a few issues: 1. The realtime DB key does not appear to have a slash ( / ) between the values. 2. There are muliple asynchronous calls to the realtime db. This will cause a lot of issues (see related thread and solution [Wrapping Asynchronous (then do) blocks into a Synchronous Function resolves unpredictable results](http://community.thunkable.com/t/wrapping-asynchronous-then-do-blocks-into-a-synchronous-function-resolves-unpredictable-results/910511)) 3. Try using the CLOUD blocks. They are easier, faster, and more reliable. Here is how to make a straight conversion from realtimedb to cloud variables [Thunkable Hack - Deep Firebase JSON data manipulation without using GET or SAVE Blocks](http://community.thunkable.com/t/thunkable-hack-deep-firebase-json-data-manipulation-without-using-get-or-save-blocks/975738) ---

@roumak-coder, Firebase shows the contents as tree like structure or file folder appearance. However, when coding you need “/” between keys and sub-keys or nodes and child-nodes Example: main-key/sub-key/sub-sub-key Hope that helps to clarify. ---
