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);

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