How to solve Error in arduino

[yugi123]

I am using Arduino pro mini controller :using analog pin:A0,A1 to control two stepper motor forward and reverse condition but i am facing one issue in program side .
I give the code. Please anyone give the logic & problem debuging .

#include<EEPROM.h>
#include <Stepper.h>
#define STEPS 32
#define Pot1

#define AnalogSensorPin_0 0

#define AnalogSensorPin_1 1

int present_Val_0 = 0;
int present_Val_1 = 0;
int past_value_0=0;
int past_value_1=0;
int var1,var2;

Stepper stepper_0(STEPS, 6, 8, 7,9);
Stepper stepper_1(STEPS, 2, 4 ,3,5);

void fun_0(int pot_0)
{
int _step,past_value_0=0;
_step=pot_0-past_value_0;

if (_step>past_value_0)

stepper_0.step(_step);

else if (_step<past_value_0)

stepper_0.step(_step);

past_value_0=pot_0;

EEPROM.put(2,past_value_0);
return past_value_0;
}

void fun_1(int pot_1)
{
int _step,past_value_1=0;
_step=pot_1-past_value_1;

if (_step>past_value_1)

stepper_1.step(_step);

else if (_step<past_value_1)

stepper_1.step(_step);

past_value_1=pot_1;

EEPROM.put(3,past_value_1);
return past_value_1;
}

void setup() {

// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
stepper_0.setSpeed(200);
stepper_1.setSpeed(200);
pinMode(AnalogSensorPin_0, INPUT); // declar the input pin
pinMode(AnalogSensorPin_1, INPUT);
past_value_0= var1;

past_value_1= var2;
EEPROM.get(2,var1);
EEPROM.get(2,var2);
}

void loop()
{
present_Val_0= map(analogRead(A0),0,1024,0,1024);
present_Val_1 = map(analogRead(A1),0,1024,0,1024);

fun_0(present_Val_0);
fun_1(present_Val_1);

var1=fun_0(present_Val_0);
var2=fun_1(present_Val_1);

}
Now compiling the code but indicating some error but i can't find it.

The functions fun_0 and fun_1 both have return statements, but the return types are specified as void.

Please reformat the code with code tags </>

1: post the code properly please - in the IDE Edit - copy for forum
then paste into the new comment field

2: comment your code so others (and yourself later) will know what its supposed to do.

Thanks for your answer, I changed tag.now fun code works.

Now you can have fun with your project.

okay
