Hi guys, I have been working on this for 13 hours straight now, and I am going out of my mind. I have a final due tonight and I cannot figure this out at all. The program is basically a product database for a sporting goods store, and I have to store all of the data in a struct record, then put in it a binary file and display all of the records as a report when the report() function is selected from the menu. Problem is my report() function is completely messed up and it displays a weird jumbled report a bunch of times and then exits out to the menu. I have to figure this out, please help me!

// ** Prototypes **

void heading(void);
int menu();
int add();
void report();
void getstring(char entry[], char prompt[]);
int getint(int min, int max, char prompt[]);
double getreal(double min, double max, char prompt[]);
double total(double quantity, double amount);
double profit(double profit_cost, double profit_price);
void init_costs(double t[], int x);
void show_costs(double t[], int x);
void show(int prodnum, int prodtype, char prodscrip[], int prodquan, double cost, double price, double prod_price, double prod_cost, double prod_profit);
int menuerror(int min, int max, char prompt[]);
int prompt(char msg[]);
int quit(void);
void message(char msg[]);
void firstUpper(char *buf);
void line(char c, int t);

struct sports
{
    int prodnum;
    int prodtype;
    char prodscrip[20];
	int prodquan;
    double cost;
    double price;

Note: The limits file looks like this:

1 9999
1 5
1 50
5.00 900.00
6.00 1000.00
