"If sentence" error

Hi,
I have a problem. I want to rename some files and this is my code. The problem is the if sentence doesn't work at all. The result is always 21 and that's not possible. I've tried to change the operand & to && but it doesn't work neither.
myPath = 'C:\EXERCICES\';
a= dir (fullfile(myPath,'*.zip));
fileNames = { a.name };
for k = 1:length(fileNames)
n = num2str(fileNames{k}(4:9));
if n >= 205040 && n < 208041
fileName = 18;
elseif n >= 203031 && n < 205030
fileName = 19;
elseif n >= 199031 && n < 202030
fileName = 20;
else n >= 196033 & n < 198033;
fileName = 21;
end
xs= num2str(fileName);
newFileName = [fileNames{k}(4:9) '_' fileNames{k}(10:16) xs '_gsd60_std' '.zip];
movefile([myPath fileNames{k}], [myPath newFileName]);
end
if true
% code
end
Does somebody know what I'm doing wrong? Thanks in advance and regards,
Emma

In your code, n is a string (you make it a string with num2str). In the if statement, you compare n with a number, so it will always be false... My guess is that you wanted to use str2num or str2double instead ;).
