Runtime Error while sending the data to the server or data base(thingspeak)

Whenever I run the app and click button 1 it shows me the value although not in the way I want it to show. and when I click button 2 and try to upload a new value it stops and shows runtime error.

Might help if you show the runtime error....


sorry this is the issue

whenever i tried to enter the value it suddenly crashes. But is uploads the latest value that I entered

Try just setting your responseContent to a label, it could be that you are not getting back a dictionary when you send a value to update.

okay I'll try


Still got the same issue

I mean like this:
