Error with Serial does not name a type

[iamiretheo]

What did you have to change in order for it to c0mpile without errors?

What fixed the "Serial does not name a type" error?
I'm having the same problem with my code:

#include <Brain.h>
#include <Servo.h>

///////////////////////////////////////////////////////
// mindflexservo
///////////////////////////////////////////////////////

Serial.begin(9600);

myservo.attach(9); // attaches the servo on pin 9 to the servo object
pinMode(12, OUTPUT);
pinMode(11, OUTPUT);

void loop() { // Expect packets about once per second.
// The .readCSV() function returns a string (well, char*) listing
//the most recent brain data, in the following format:
// "signal strength, attention, meditation, delta, theta, low // alpha, high alpha, low beta, high beta, low gamma, // high gamma"

if (brain.update()) {

 // Serial.println(brain.readErrors()); 
 // Serial.println(brain.readCSV()); 		
 //sprintf(a, "%c",brain.readCSV()); 

a = brain.readCSV(); 

v = a.indexOf(','); 
v = a.indexOf(',',v+1); 
v = a.indexOf(',',v+1); 
v = a.indexOf(',',v+1); 
z = a.indexOf(',',v+1); 

a1 = a.substring(v+1,z); 
num = a1.toInt(); 			 
v=a.indexOf(',',z+1); 

a = a.substring(z+1,v); 

num1 = a.toInt();
Serial.print("alpha =  "); 
Serial.println(num1); 		

output = map(num,0,999999,0,180); 

myservo.write(output); 	// tell servo to go to position in variable 'pos' 

delay(15); 

 // analogWrite(12,output); 

//brain.readCS).toCharArray(a,200); 

}
And I m receiving the following compile errors

You forgot to put your code inside setup().

Outside function declarations you can only have variable declarations.
