Cell contents reference from a non-cell array object. error in loop

hi there, so i want to extract a 1*3 double from a cell array, but in the loop i get the error shown above, any help?

   for i=1:length( c )
            d=some_cell{i,1}{1,1};
end

Apparently some_cell{i,1} does not contain a cell, or some_cell is not a cell itself. If you don't show some actual code, we won't be able to help you.
