Here is my code:

How can i solve the problem:

C:\Users(…)\Arduino_Yun\Arduino_Yun.ino: In function ‘void BlynkWidgetRead2(BlynkReq&)’:

Arduino_Yun:57: error: ‘param’ was not declared in this scope

Serial.println(param.asStr());

Hello. Does simple sketch without your code compiles fine?

What is that?
