nothing is showing up, idk why
Yes, it will not .. please read my fb structure , images and the get value block then compare with your fb structure., Images....(you will come to know your mistake) put the slash symbol in correct manner. Please read all the replies patiently.. (we will not suggest anyone the not working blocks 
)
Single calling block lone is enough. No need to use fb block according to the length of the subtags.
Call firebase get value (Events)
If not found, call empty dictionary
That's all, when firebase get value.. (same blocks but keys name alone have to change )
i cannot call just "Events", i want to call a specif subtag, thats why i used Events/"classnumber"
Although, even though i changed to the same as yours, i still get no value.. 
Can you share your demo aia?? Or have you used my aia , made changes ?? Or can you give your fb json download from the fb??
Earlier you asked for all the, now asking specific tag... Pls read my very first suggested image, there i did for specifi tag. Yesterday you said, if i add new values .. so changed the algorithm
i did this, exactly as you said. didnt work
3.5MB means, this is seems to be main aia. We do not encourage the users to send main aia, pls send us demo aia.. also here my creator will lag for MB size aia (due to low memory ram and week network)
Ah, dont worry then, it seems like i cannot send the demo file due to my school pc for some reason not allowing it, but anyways, ive done the same thing as you stated here:
As you can see in
Yes i did change the Tags, they are like this now:
Just as you stated, ive watched your reply carefully, and i still get " " as a value, i do not know whats wrong.
What did you do?? whats wrong with it?? 
i simplified your codes like this..
(as i suggest you very first, you want to read for specific tag)
Do not clear this bucket from designer page, else you will get error

Your reduced size aia
cool. but noticed the IF statements checking if my start value is either 301-305..
thats because in my Development app (the one that sends the info) will send different infos using different tags (301-305 are my classroom number, therefore each one of them being different classes, so by logic, it will be different info) Thats why the if statement.
Did you test it? Working?
If the tags under each classes is common mean , directly you can use the same block. In future if you will use some strong instead of number as tag mean, then here you can slightly adjust like that, Is number???
Anyway , you can design your own logic.
How did you sort the tags out?
Links should have "Youtube"
And Noticia should have whats on Links
Could you explain it @Spicy_Topics
So about this one, now im doing the "Calendario Semanal" part.
notice how i have unwanted ( \n ) on the string?
Mostly because i have this enabled:
So i wanted to take that out from my value? How do i do that?
Note: Its just a single tag, so its not as complicated as the other ones
Just use replace text block
Is there a way to make it so if i send a link, the other app receives a hyperlink?
