Timer0 as counter with Microchip PIC10F202 - counter

Question

I developing RC switch for my RC glider.
I have microkontroller Microchip PIC10F202 and I have problem with ON/OFF LED Lights.
I want triggering input PPM signal from RC receiver, I setted GP2 as input (by T0CKI and count for every rise edge - from low to high), but LED is still ON, not reacting on input signal from RC receiver.
I post my source code in C language, I can not ASM language.
// this is header file with some macros and function prototypes
#ifndef XC_HEADER_TEMPLATE_H
#define XC_HEADER_TEMPLATE_H
#include <xc.h>
#define _XTAL_FREQ 4000000
#define KONST_ON 50
#define KONST_OFF 1000
#define STROBO_LED GP0
#define NAVI_LED GP1
#define RC_SIGNAL GP2
#define STAV_ON 1
#define STAV_OFF 0
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
}
#endif
void setup ();
void flashing ();
#endif
// In this function is setup for microkontroller
#include <xc.h>
#include "prototypy.h"
void setup ()
{
OSCCAL = 0b0111111;
//STATUS = 0b00111000;
OPTION = 0b11100111;
TRISGPIO = 0b0000;
};
// This is function for LED flashing
#include <xc.h>
#include "prototypy.h"
void flashing ()
{
__delay_ms (KONST_OFF);
STROBO_LED = STAV_OFF;
__delay_ms (KONST_ON);
STROBO_LED = STAV_ON;
};
// in this main function I do logical product, where I have logical state from pin GP2 and number 1
#include <xc.h>
#include "prototypy.h"
// Code protection bit
#pragma config CP = OFF
// Watchdog timer
#pragma config WDTE = OFF
// Pin function
#pragma config MCLRE = OFF
void main ()
{
setup ();
while (1)
{
if (RC_SIGNAL & 1)
{
flashing ();
}
}
}
Please, can me someone help and found error in my source code?

I'am not really familar with that devive, but I guess you Pin RC_SIGNAL is not configured as an Input. Please try
TRISGPIO = 0b0100;
