Having trouble using the struct function, to structure my data set.

% using the excel data 
[FileName, PathName] = uigetfile('*.xlsx','Select Excel files to analyze:','MultiSelect','off');
[status, sheets] = xlsfinfo([PathName, FileName]);
summary_data = xlsread([PathName, FileName],sheets{1});

Volume = summary_data(:,1); % in mL
Time = summary_data(:,2); % in Seconds 
Power = summary_data(:,3); % in watts;
numsheets = length(sheets);
data(numsheets-1) = struct('Volumes',[],'Times ',[],'Powers',[]); 
 
for j = 1:numsheets-1 ;
    rawdata = xlsread([PathName, FileName],sheets{j+1}); 
    data(j).Volumes = rawdata(:,1);
    data(j).Times = rawdata(:,2);
    data(j).Powers= rawdata(:,3);
end

%% error  I get After running 
Error using struct
Invalid field name "Times "

Error in Lab1 (line 11)
data(numsheets-1) = struct('Volumes',[],'Times ',[],'Powers',[]);

You have 'Times ' in the struct() call. Change it to 'Times' with no space.
