else-if sentences issue

hi,

i'm adapting thermometer code arduino uno makeymakey in order make tests have problem when working on it. code next:

code: [select]


#define analogpin 22    //23 18 pins related mouse
                                    //the 22 1 labeled a4
#define beta 3000
#define resistance 47 //it in ohms

int lastreading=0;
boolean loggingon=false;
int period=300;
int count=0;
int span=20;

void setup()  {
  pinmode(ledpin, output);
  pinmode(analogpin, input);
  serial.begin(9600);
  serial.println("listo");
}

void loop()
{
  if(serial.available())
  {
    char ch=serial.read();
    if (ch == 'g' || ch == 'g')
    {
      loggingon = true;
      serial.println("logging started");
    }
   
    else if (ch == 'm' || ch == 'm')
    {
      //changes ammount of values used compute mean
      serial.println("cantidad de valores promediar: ");
      char newspan=serial.read();
      span = newspan;
    }
   
    else if ((ch > '0') && (ch <= '9') )
    {
      setperiod(ch);
    }
   
    else if (ch == '?')
    {
       reportstatus();
    }
  }
 
 
  if (loggingon && count>period)
  {
    logreading();
    count=0;
  }
  count++;
  delay(1000);    //mirar en arduino.cc para usar otra cosa que no es delay
}


where have discarded functions defined me. anyway, when type 'm' wanto change number of values used calculate mean, when type in numerical value, program jumps next else-if sentence sample period changed. don't understand what's wrong , appreciated.

i must i've been having troubles , misbehaviour sketch since working on makey, although worked arduino uno. i'm not sure if problem may in ide (it not hte latest version) sounds strange me.

i hope me. thank time.

do have "no line ending" option set in serial monitor?
