That project is working well seperately but when merging it into my project am getting that error

[SteveJG]

You have the FirebaseDB.FirebaseDBError enabled in your code. You presently do not link the message to display on a Label. When you do not set message to a Label, and do not use its message, you suppress any runtime errors from displaying. Essentially your app ignores any errors.

To view firebase's error messages you need to either disable the Block or set code in it's event handler to send the error to a Label.

If you disable the FirebaseDBError Block, . you should see a message from firebase like this one.

Alternatively you can show the message in a Label. (Set the message in the Block to display on a Label. (without disabling the Block))

HI @SteveJG
I added the firebase error message as you requested but still getting the same issue and while blocking it as well i got the same error

Search through your blocks for your blue 'list from csv row' blocks, one by one.
Use the Companion Do It feature to show what you are feeding it.
Pay particular attention to commas and quote marks.
Are the quote marks balanced?

the aia file i attached above working well separately but once adding it to my project, its showing the error above, i didn't change anything in the blocks i just copied all blocks to a screen in my project

@mustafaalbasel

i didn't change anything in the blocks i just copied all blocks to a screen in my project

well, something is different
is it something with Firebase? is it something else?
to find out what exactly, you have to debug the project

so what about answering the following question?

@Taifun

When exactly does the error occur?

Then start to debug from the corresponding event

Really I didn't change anything even didn't change anything in the firebase..let's try to merge the aia project above in any sample project do you have if it works well then the issue is in my project, but if it showed the same error then we can find out why is that error occured!

[Taifun]

@mustafaalbasel

Really I didn't change anything

you are repeating yourself
start doing something now!
read again my previous answer and answer the question

@Taifun

When exactly does the error occur?

Taifun

[mustafaalbasel]

After adding the project immediately into my project...it never worked after adding it to my project getting the same error

[Taifun]

@mustafaalbasel

After adding the project immediately into my project..

without testing in the companion app? without starting the test in Screen1 and continuing to that new screen?

you named that screen find
this probably is not a good idea, because find might be a reserved word...
remove that screen again and use another screen name, for example ScreenFind

@Spicy_Topics
lets check the aia file please
Sampleproject2.aia (5.2 MB)
the aia project, screen1 for the location is working well when it is being screen1 but i don't wanna make it the main screen so when i changed it to another screen than screen1, it doesn't work, don't know the reason, lets check it in the aia file please

[mustafaalbasel]

i renamed it to Screen2 but didnt work as well, the issue isnt in the name

[Spicy_Topics]

Sampleproject_1(1).aia (5.2 MB)

Pls test aia whether working or not..

[mustafaalbasel]

@Spicy_Topics still getting that error

lets open that aia file i sent in that comment to see how it is working and try to move it to another screen to see why is the error appearing

just write a name in the textbox and press add driver then if you pressed find or post,
Sampleproject2.aia (5.2 MB)
it should work without an error

[Spicy_Topics]

Ok, i was wrongly understand your query to move contents from screen1 to other screen

[Spicy_Topics]

i clciked button 3 and button 14 but no such errors in my companion.

[mustafaalbasel]

@Spicy_Topics After moving it to another screen than screen1?
It works well being in the screen1 only with me

[mustafaalbasel]

@Spicy_Topics
So can you check blocks please to see why am getting the error in the screenshot above when changing it to another screen than the first screen?

[Spicy_Topics]

See, i have tested in both the version.
Your version Screen1 i get no such error
My Version Screen2 too didnt get such

After entering name and press Button 3 as well as Button 14

[Spicy_Topics]

i believe it is not because of screen. Youare using relevant blocks at here

But you are adding values to this variable as a list only but are adding value into this variable as a list only

then what is the role of list from csv row text @mustafaalbasel ?

[mustafaalbasel]

@Spicy_Topics I didn't make that project so I don't know it's concept
@SteveJG who helped me for it
So all I want to make it worked in the screen2 same as it's working in the screen1
