need help, want to call program in void setup to voif loof

so day spending few hours solve how make intruction im need call void loop,
i mean write down program on void setup, after in void loop need make if statement, example if a<b call foward();. , foward program write in void setup. understand mean see program.

code: [select]

void setup() {
  // put setup code here, run once:
serial.begin(9600);
void motion1() {
digitalwrite(12, low); digitalwrite(13,high);delay(100);
digitalwrite(12, low); digitalwrite(13,low);delay(100);}
void motion2(){
digitalwrite(12, high); digitalwrite(13,low);delay(100);
digitalwrite(12, low); digitalwrite(13,low);delay(100); }
}

void loop() {
  // put main code here, run repeatedly:
int valuesensor1 = analogread(a0);
serial.println(nilaisensor1);
serial.print("nilai sensor =");
if(valuesensor1 > 500){motion1();
}
if(valuesensor1 < 500){motion2();
  }
}
in cvavr wok, need arduino ide, lot

you can't define function inside function.
