'serial' was not declared in this scope

nello Sketch non riesco ad usare le funzioni "serial.print". Ho incluso queste librerie ma mi continua a dare sempre questo errore:

'serial' was not declared in this scope.

Qualcuno può darmi un aiuto ?

Grazie per l'attenzione.

Serial.print instead of serial.print

sorry Coding Badly, I formulate better demand:
The compiler do not admit the instruction "serial.print". At the begin on the sketch I wrote the instruction "#include SoftwareSerial.h" but the problem remains.
Can you help me ?
P.S. sorry for my bad english

Rather than struggling to communicate I suggest posting your question in the Italian section...

Utilizzare una lettera maiuscola (Serial.print)
