I am facing an issue in firebase append value block i cant add multiple values under diffrent tags. I used a label text to tag and value but not working please give any solution
Thankyou.
Can you show us your work, Interms of blocks
Show your blocks for what you are trying to achieve, and what you expect your firebase structure to look like.
Confirm you are working with AppInventor (not Kodular - that has a different firebase component)
Iam not using kodular
Iam working with app inventor
I want to add miultiple append values using firebase like this
Example:
users
User1: 1/2/3/2/4/
User2: 3/7/9/0/9/0/
User3: 3773/37373/3838
This is my blocks
individual list items ? e.g.
tag: Users/User1 value: [1,2,3,4]
then append a value:
tag: Users/User1 value: [1,2,3,4,5]
The problem is you cannot use this slash to append. Firebase will set as new tag if you use slash. So as said by taifun method follow
I have one doubt if users are from multiple devices how to change this blocks to a text box as tag. users enter her name as tag
Use login method. Validate the login. If success, set their name as tag name. Without login or authentication it will be harder to unit them all

Will you provide some blocks for understanding
1 = First time used to store the value as a Yailist (Yailist only can be appended)
2 = Append data in the same tag

I add value to firebase But when appending showing "previous value was empty" Error
What is the solution for this?
I've said it earlier. You have not saved the previous value as a yail list. For your ref only i have given you the blocks above
You must save the value as yailist so that you can append later
