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 Kodular, open it, do some bug hunting for you, etc… this takes time, and most people will not do that…
Thank you.
To follow up on the great advice from Taifun…please only ask in the community of the builder you are using. You have also asked this on Thunkable 5 days ago and been given an answer.
what about displaying the response content for mobile data in a label to find it out yourself?
and to display a “nice” error message, you also can check if the response content contains the text “data-exchange-rate” … you can find the contains block in the text drawer…
