conflicting declarations for variable "DisplayData"

求知道pic16f877a編譯程序錯在哪裡
程序如下：
#include<pic.h>
void delay();
void Display(unsigned int iData);
__CONFIG(0x1832);
void main()
{

  unsigned int  iData=1234;
  TRISC=0X00;
  TRISD=0X00;
  PORTD=0X00;
  PORTC=0X00;
  while(1)
  {
   DisplayData( iData);
  }
}

void DisplayData( unsigned int iData)
{
const char Seg7TableN[]={0x3F,0X06,0X5B,0X4F,0X66,0X6D,0X7D,0X07,0X7F,0X6F};
int i=0,j=0,k=0,Numstr[]={0,0,0,0,0};
Numstr[1]=(iData)/1000;
Numstr[2]=(iData%1000)/100;
Numstr[3]=(iData%100)/10;
Numstr[4]=iData%10;
for(i=0;i<10;i++)
{
   PORTD=k=0X01;
   for(j=1;j<=4;j++)
   {
      PORTD=k;
      PORTC=Seg7TableN[Numstr[j]];
      delay();
      k=k<<1;
   }
  }
}
void delay()
{
int a;
for(a=0;a<500;a++);
}
該程序是用數碼管顯示一個4位數字，可編譯總還是通不過并提示如下：
