inputToken was not declared in this scope


I am brand new to all of this, coding, arduino and ESP8266.

I have just made a simple circuit in the app and downloaded the code. The code won’t upload to the Arduino and all it says is " ‘inputToken’ was not declared in this scope "

I guess I can define it, but like I said, I am a total noob.

I am running this on an Arduino Pro Mini ( I wanted it to be small for my project )
With the ESP8266-01 module
The circuit also has a Logic Level Converter.
I through on an LED to the project just for kicks.

If anyone has any ideas, I would love to hear them and learn! So thank you in advance!
