two dimensional array inside a struct -- extremely WEIRD! please help, im stuck!

Code:

struct MAP
{
	int maparray1[20][56];
	int maparray2[20][56];
	int maparray3[20][56];
	int maparray4[20][56];
	int north;
	int south;
	int east;
	int west;
};

MAP map1;

for(int a=0;a<=20;a++)
{
	for(int b=0;b<=56;b++)
	{
		map1.maparray1[a][b]=a;
	}
}

this is just one way I tried to initialize the array. I also tried doing map1.maparray={0,0,0,0,.....etc.}; and all of the possible ways i knew to initialize arrays. for all of them it gives me errors like:
c:\documents and settings\john\desktop\keldan\map.h(15) : error C2143: syntax error : missing ';' before 'for'
c:\documents and settings\john\desktop\keldan\map.h(15) : error C2143: syntax error : missing ')' before ';'
c:\documents and settings\john\desktop\keldan\map.h(15) : error C2143: syntax error : missing ';' before 'constant'
c:\documents and settings\john\desktop\keldan\map.h(15) : error C2143: syntax error : missing ';' before 'constant'
c:\documents and settings\john\desktop\keldan\map.h(15) : error C2059: syntax error : ')'
c:\documents and settings\john\desktop\keldan\map.h(16) : error C2143: syntax error : missing ';' before '{'
c:\documents and settings\john\desktop\keldan\map.h(16) : error C2447: missing function header (old-style formal list?)
Error executing cl.exe.

also when i try to initialize it different ways, it says things like i'm redefining MAP, and odd things like that. is there some special way for doing this? thanks.

I don't have any problems with your given code, could you post some more?

-Prelude

try this,

struct MAP map1;

for(int a=0;a<=20;a++)
{
...

Two problems

1. Your code is
a) inside a .h file
b) outside a function

2. your loops are too big - you're one off the end of each array
for(int a=0;a<=20;a++)
should be
for(int a=0;a<20;a++)
