想实现单片机100-0循环，不知道错在哪里？附原理图

#include<reg52.h>
unsigned char code DuanMa[16]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0x88,0x80,0xc6,0xc0,0x86,0x8e,};
unsigned char number;

void Delay(unsigned int t)
{
  while(t--);
}

void DisplaySMG(unsigned char dat,unsigned char pos)
{
  P2=(P2&0x1f)|0xc0;
  P0=0x01<<pos;
  P2=(P2&0x1f)|0xe0;
  P0=dat;
}

void dynamic()
{
  DisplaySMG(DuanMa[number/100],1);
  Delay(200);
  DisplaySMG(DuanMa[number%100/10],2);
  Delay(200);
  DisplaySMG(DuanMa[number%10],3);
  Delay(200);
}

void delay2(unsigned char t)
{
  while(t--);
  {
   dynamic();
  }
}

void main()
{   number=0x64;
   while(1)
  {        
        Delay(200);
        dynamic();
          number--;
    if(number=0)
    {
    number=100;
    }
    delay2(60);
  }
}

if(number==0)number=100;

if(number==0)number=100;

谢谢！！
