Problem with 2d array

I declared the array but when I try to access different indexes with for loop, it doesn’t work.

test.ino (349 Bytes)

 lcd.print(L_value[99][1]);

That’s way outside the bounds of your 10 x 10 array.

  for(int i=0;i<sizeof(L_value);i++){
  for(int j=0;j<sizeof(L_value);j++)

Just what does sizeof() report for you? The array is 200 bytes. You can’t loop over a 200 x 200 array when it is only 10 x 10.

Thanks
