comparing string with cell from table

I like to find how many times the word TC is present is column 4 of the table data. The counter stays on zero. Can someone pleae tell me why? I wrote this code:

for YY=1:z
  TC{1,YY} = (0);
  [rowX, columnY] = size(data{1,YY} );
  for qq = 1:rowX
    vvv{1,1} = data{1,YY}(qq,4);
    Index2{1,1} = strcmp(vvv{1,1}(1,1), 'TC');
    if Index2{1,1}==1
      TC{YY} = TC{YY}+1;
    end
  end
end

What is "data"?

What about:

TC = zeros(1, size(data, 2));
for YY = 1:size(data, 2)
  col4   = data{1, YY}(:, 4);
  TC(YY) = sum(strcmp(col4, 'TC'));
end

data is a cell array containing z tables. I liked to search in each of this tables. You can replace YY by one if you like. TC stays on 0.

Please post the contents of the tables.
