How to use timer2 to blinking led7 whenever push a button

[phithuc]

Hi all!
I'm using 16F877A. I write a program to blink led7 when push a button . I use timer2 with set up:
void Init_Timer(void)
{
setup_timer_2(T2_DIV_BY_4, 250, 1);
enable_interrupts(GLOBAL);
enable_interrupts(INT_TIMER2);
}
and isr as the following:
void timer2_isr(void)
{
Flag=~Flag;
}
and in scan routine I write:
Switch (ModeValue)
{
case 1:
{
clear_interrupt(INT_Timer2);
output_high(PIN_E0);
SetHour();
ds1307_set_date_time(day,mth,yr,dow,hr,min,sec);

Init_Timer();
if(Flag==true)
{
if(level==0) level=1;

}

break;
}
Progam runs, led blinking. but sometime led7 don't lighten when I push button. Please help me how to drive a interrupt, stop it whenever I want. Thanks!!
