一段小程序，出错了，各位帮帮忙

int price_cacl(IRDA_ELECT Irda_elect,PFOUINFO pFouinfo)

{

	float flat;

	flat = atof(Irda_elect.total)-atof(Irda_elect.high)-atof(Irda_elect.low);

	printf("T is %s--H is %s--L is %s--F is %f\n",Irda_elect.total,Irda_elect.high,Irda_elect.low,flat);



	printf("prc_code is %s\n",pFouinfo->usrinfo.prc_code);

}



main()

{

	IRDA_ELECT Irda_elect;

	FOUINFO Fouinfo;

	memset(&Irda_elect,0x00,sizeof(IRDA_ELECT));

	memset(&Fouinfo,0x00,sizeof(FOUINFO));

	

	sprintf(Irda_elect.total,"%s","80");

	sprintf(Irda_elect.high,"%s","20");

	sprintf(Irda_elect.low,"%s","20");

	sprintf(Fouinfo.usrinfo.prc_code,"%s","40101019");

	price_cacl(Irda_elect,&Fouinfo);

}

出现如下错误：
price.c: In function `price_cacl':
price.c:65: error: dereferencing pointer to incomplete type
price.c: In function `main':
price.c:79: warning: passing arg 2 of `price_cacl' from incompatible pointer type
查了下说是结构体的问题，但是找不到原因...
