I need help with a created function I made. Could someone please tell me what I did wrong?

I created a function to put all of my ascii files I have in one folder into one larger file with the data in the correct sequence. I got an error on the first line, though, so I can't run it. My code should be right if I can eliminate this error. The error reads: Error using read_test_data_jp (line 32) Not enough input arguments. I can't provide the files that I'm using or the info in them, but I tried to make some dummy ones to look at.

function read_test_data_jp('Y:\Prelaunch\Drive_Acceleration\ML Move to and from Pad B\read_test_data_jp') % start_directory – path to data

AllFiles = [];

filenames = dir('Y:\Prelaunch\Drive_Acceleration\ML Move to and from Pad B\MovetoPadB-ascii'); % starting directory

for ii = 3:length(filenames) % Start at third file( i.e., don't include "." and "..")

%Get the filename

filename_timestamp = filenames(ii).name;

% parse data filename_timestamp for the timestamp information

semicolonIndex = findstr(';',filename_timestamp);

commaIndex = findstr(',',filename_timestamp);

day = str2num(filename_timestamp(1:semicolonIndex(1)-1));

hour = str2num(filename_timestamp(semicolonIndex(1)+1: semicolonIndex(2)-1));

min = str2num(filename_timestamp(semicolonIndex(2)+1: semicolonIndex(3)-1));

sec = str2num(filename_timestamp(semicolonIndex(3)+1: commaIndex(1)-1));

% read space or tab-delimited data; if tab use '\t' instead of ' '

DataFile = dlmread(fullfile('Y:\Prelaunch\Drive_Acceleration\ML Move to and from Pad B\read_test_data_jp',filename_timestamp),' ');

% Now correct the first column of data by adding the seconds that were read in from the file name

DataFile(:,1) = DataFile(:,1) + day*86400.0 + hour*3600.0 + min*60.0 + sec;

% Append files as you loop through all of the files into one matrix

AllFiles = [AllFiles;DataFile];

end

%Write tab delimited data to a file

dlmwrite('Appended_Test_Data_Output.txt',AllFiles,'delimiter','\t'); end

A function has to take a variable name as argument, not a hard-coded string. You then call it with the string you want to pass in, running it from command line or a script or another function.
