Loop in a cell array that consist of matrices in each cell

I have written a loop to extract data from a 24x1 cell array, where each cell is of 36000x16 double table. I want to find the maximum value of column 12 in each of the 24 cells and store them in a matrix. But I'm getting an error 'Array indices must be positive integers or logical values.'

%% Loop for extracting data from a cell array
% results is a 24x1 cell array. Each cell consist of 36000x16 double table 
for k =1:numel(results)
    t = results{k,:}; % extracting every matrix within a cell
    % values of interest is in column 12
    temp = t(2:end, 12:12); 
    
    % find maximum value
    max_column = max(temp);
    
end

You have a variable called "max" previously defined in your workspace.

Easier:

results=cat(3,results{:});
max_column = squeeze(  max(results(2:end,12,:))  )
