dude ur amazing i just looking for the deadband code

void Motor()
{
	val1=analogRead(Poti1);
	val2=analogRead(Poti2);
	if ((val1>val2)&&(val1>minval))
	{
		Motor_1_3();
	}
	if ((val1<val2)&&(val1<maxval))
	{
		Motor_2_4();
	}
	if ((val1=val2)||(val1=minval)||(val1=maxval))
	{
		Motor_OFF();
	}
}

one question can i put val = analogread to a different void or this wouldn't work
