Hello friend, I have this problem that I've been trying to solve for days. I beg for your help
BINGO (4).aia (1.4 MB)
If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...
which means in your case post a screenshot of your relevant blocks...
To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.

you are using iOS, I now changed the category to App Inventor for iOS
sorry, I'm not able to help here

but no matter where I run the app it still gives me that error sorry for the inconvenience
I blame this code.
Apply Do It to the TinyDB1 value, and show us what it returned.
The if/then block only eats true/false values.
Here is what you store in that tag:
So this should work better:
The "type boolean" phrase led me to search for an unhappy if/then block, since they are the only type of block that eats booleans (mostly.)
There were no empty sockets, so had to be indigestion.
THANK YOU BUT IT SEEMS THAT IS NOT IT EITHER. I GET THE SAME ERROR
GET VALUE
I GET THIS ERROR WHEN I RUN THE APP ON MY CELL PHONE
I stopped looking at the first error.
Did you check the rest of the TinyDB checking in the other screens too?
If after thoroughly checking for that error elsewhere in your app it reoccurs, export the revised aia here for some one to read.
For faster service, do a clean up blocks on every screen and post the downloaded block images of all screens.
I had some extra time, and access to my large screen desktop, for a more detailed examination of your blocks.
Reading what you code is a necessary habit.
You made the same mistake in many places.
This email address validator has the text Contains block inputs reversed.
More of the same error as earlier:
When the same error is rubber stamped across a project, we call it a Platinum Jubbly:
In this block, I see evidence that either you have a color blind team member unable to distinguish between red text blocks and orange variable blocks, or some one who does not know the difference:
The person who coded this apparently did not realize that the screen initialize block runs first in a screen, so any global variables it accesses will have whatever unchanging value was coded into those variables' init global blocks.

from the free online book.
This error in iOS typically occurs because one uses a component that isn't implemented, either something like FirebaseDB or an extension. looking at your MENU screen, it looks like you are using AbsoluteArrangement. That won't be in iOS until our next iOS companion update next month.
