I am trying to use Airtable to store account information of different users. I’ve tried to test it with multiple devices, and although it worked for a few cases, it stores the “username” field as “null” even when there is data input from the app most of the time.
Hi, @renren66! 
My Chrome cannot open your project 
(It’s just loading a blank image with lots of orange, yellow ochre blocks)
It seems you have used a lot of variables, that makes your project crash on mine…
So Can you please provide a screenshot of your blocks of button2?
Thanks! 
Your blocks in Buttin2.click very complicated and duplicated - Alert bunch, bunch of action, some obscure check for null.
In programming, there is a recommendation - in every function you should try to perform only one operation, because the more complex the function, the much more difficult to look at her mistakes. Throw bugs Thukable X and will be very difficult to understand where your mistakes, and where the system error. For this reason, as variables I use function blocks and parameters only in case of emergency use global variables.
Create a simple function check, create a new row to be accurate or not.
If the database is recorded null, it means that the stored-block is not initialized (it nothing was written) or for whatever reasons, null is written in it. Blocks of global variables become unstable and I would not be surprised if it’s a bug system. For this reason, as variables I use function blocks parameters and only in case of emergency use global variables.
Why working with Thunkable X (and not only), you need to check everything and do not trust your eyes?
I give a simple example.
Label1.Text “undefined” display on screen, and how many characters will return the block length of?
Another example - screen component has such a configuration
Does this mean that the padding on Android are equal to 0? No! But how can this be, we’re seeing 0 in the fields! You can draw anything you like, but this does not mean that it is in reality.
