Put triple backticks at the beginning and end of the the error message test so that it displays correctly. Triple backticks look like this:
Copy and paste these if you can’t find the correct symbol on your keyboard.
Also, add your sketch, also with triple backticks at the beginning and end, along with details of the hardware you are using and the version of the Blynk library you have installed.
