IR Remote coding question

hello all,

i working on project uses ir remote control up/ down counter ic. i'm working following code:

code: [select]

#include <irremote.h>

int irpin = 11;  // pin ir sensor
irrecv irrecv(irpin);
decode_results results;

void setup()
{
  serial.begin(9600);
  irrecv.enableirin(); // start receiver
 
  pinmode(13, output);//counter up
  pinmode(12, output);//counter down
  pinmode(10, output);//reset
 
  digitalwrite(10, high);
  digitalwrite(10, low);//reset counters
}


void loop()
{
   
  if (irrecv.decode(&results))
    {
     
      irrecv.resume();   // receive next value
    }
 
  switch(results.value)
 {

  case 1168:
  // left up
   digitalwrite(13, high);   // turn led on (high voltage level)
  delay(10);              // wait second
  digitalwrite(13, low);    // turn led off making voltage low
  delay(500);              // wait second
  break;
 
  case 3216:
  // left down
   digitalwrite(12, high);   // turn led on (high voltage level)
  delay(10);              // wait second
  digitalwrite(12, low);    // turn led off making voltage low
  delay(500);              // wait second
  break;
 
  case 1808:
  // left +3
  break;
 
  case 304:
  //left reset
  break;
 
  }
 

the problem experiencing when hit button on remote, program seems hold remote code , continually carries out switch case code. desired effect program take input, carry out switch case once, , wait next input. suggestions on can add code desired effect?

thank you
mike

x = results.value;
.
.
.
switch (x)
{
case 1168:
  // left up
   digitalwrite(13, high);   // turn led on (high voltage level)
  delay(10);              // wait second
  digitalwrite(13, low);    // turn led off making voltage low
  delay(500);              // wait second

  x = 0;

  break;
