Problem with 2d array

i declared array when try access different indexes loop, doesn't work.

code: [select]

lcd.print(l_value[99][1]);
that's way outside bounds of 10 x 10 array.

code: [select]

  for(int i=0;i<sizeof(l_value);i++){
  for(int j=0;j<sizeof(l_value);j++)
just sizeof() report you? array 200 bytes. can't loop on 200 x 200 array when 10 x 10.
