Can't seem to loop through subdirectories and do work...

I'm attempting to loop through excel files that are contained in a bunch of folders that are all subdirectories of the c:\data folder.
To test to see if my loop is working, I am trying to generate plots for each imported file that should be executed in my forloop.
However, I cant' get the script to execute anything. I don't get any errors, but the script is not doing exactly what I want to complete.
Any help would be MOST appreciated! Here is the example code:
folder = 'c:\data';
wantedfiles = {'Angels' 'Diamondbacks' 'Orioles' 'Royals' 'Yankees' 'Mets' 'Giants'};
subdirs = dir(folder);
subdirs(~[subdirs.isdir]) = [];
for K = 1 : length(subdirs)
thissubdir = subdirs(K).name;
if strcmp(thissubdir, '.') || strcmp(thissubdir, '..'); continue; end
subdirpath = [folder '\' thissubdir];
for L = 1 : length(wantedfiles)
fileToRead1 = fullfile( subdirpath, [wantedfiles{L} '.xls'] );
if ~exist(fileToRead1, 'file'); continue; end
subplot (2,1,1), plot(Score,Allow)
title('Testing to see if it works');
subplot (2,1,2), plot(Allow,Score)
title('Well, did it?');
end
end

Although you loop through, you do not read the content of the files.
Anyhow, use the debugger to step through and see if anything unexpected is happening.

And add this line to the top of your code:
echo on;
and take the semicolon off the ends of your line. If your code is executing then something should certainly print to the command window if you do those two things. Then split this line
for K = 1 : length(subdirs)
up like this:
numberOfFolders = length(subdirs)
if numberOfFolders <= 0
uiwait(warndlg('Number of folders = 0!'));
end
for K = 1 : numberOfFolders
