possible improper syntax with filling a structure

[swellbo]

I'm getting a "field .. cannot be resolved" message. Perhaps I'm not using the proper syntax? Do I need to declare the structure in main before I can fill it in a separate function? Thanks!

struct product
{
int id_number[MAX_PRODUCTS];
char name[SIZE];
double cost[MAX_PRODUCTS];
int reorder_level[MAX_PRODUCTS];
int reorder_amt[MAX_PRODUCTS];
};

bool GetMaster (product[]){
bool file_is_open;
ifstream input_file ("ECWMaster.txt");
while (input_file){
for (int data_getter = 0; data_getter < MAX_PRODUCTS; data_getter++){
	input_file >> product.id_number[data_getter] >> product.name[data_getter] >> product.cost[data_getter] >>
	product.reorder_level[data_getter] >> product.reorder_amt[data_getter];
}
}
if (input_file){
	file_is_open = true;
}

return file_is_open;
}
