Instance does not name a type, in function void loop (8x8 matrix) Hey guys I'm doing a beginners project 8x8 matrix and I have some errors when compiling   

The Errors are;


MyBlink:0: error: 'Instance' does not name a type
MyBlink.cpp: In function 'void loop()':


-MyBlink:40: error: 'row1' was not declared in this scope

 Instance code:
//the pin to control ROW 
const int row1 = 2; // the number of the row pin 9 
const int row2 = 3; // the number of the row pin 14 
const int row3 = 4; // the number of the row pin 8 
const int row4 = 5; // the number of the row pin 12 
const int row5 = 17; // the number of the row pin 1 
const int row6 = 16; // the number of the row pin 7 
const int row7 = 15; // the number of the row pin 2 
const int row8 = 14; // the number of the row pin 5 
//the pin to control COl 
const int col1 = 6; // the number of the col pin 13 
const int col2 = 7; // the number of the col pin 3 
const int col3 = 8; // the number of the col pin 4 
const int col4 = 9; // the number of the col pin 10 
const int col5 = 10; // the number of the col pin 6 
const int col6 = 11; // the number of the col pin 11 
const int col7 = 12; // the number of the col pin 15 
const int col8 = 13; // the number of the col pin 16 
void setup(){ 
int i = 0 ; 
for(i=2;i&lt;18;i++) 
{

} 
digitalWrite(row5, LOW); 
digitalWrite(row6, LOW); 
digitalWrite(row7, LOW); 
digitalWrite(row8, LOW); 
} 
void loop(){ 
int i; 
//the row # 1 and col # 1 of the LEDs turn on 
digitalWrite(row1, HIGH);

digitalWrite(col5, HIGH); 
digitalWrite(col6, HIGH); 
digitalWrite(col7, HIGH); 
digitalWrite(col8, HIGH); 
delay(1000); 
//turn off all 
for(i=2;i&lt;18;i++) { 
digitalWrite(i, LOW); 
} 
delay(1000); 
}
MyBlink:0: error: 'Instance' does not name a type


Once I deleted the line Instance code: on the first line both errors went away.
