Counting the numbers of times a number appears in a list

Hello,

I have the following code:

clear;close;clc;

prompt = {'Enter File name:'};

dlg_title = 'Quarterly Reports';

num_lines = 1;

answer = inputdlg(prompt,dlg_title,num_lines);

file=answer{1,1};

mon=length(file);

ye=mon-4;

first=file((ye+1):mon);

FName=strcat('PSANumbers',first);

filename=strcat(file,'.txt');

f=fopen(filename);

line1=fgetl(f);

res=[];

k=0;

G=xlsread(FName);

h=length(G);

 while ischar(line1)

if ischar(line1)

     res =char(res,line1);

     idx=regexp(line1,'R[1-9]');

     for j=2:h;

         p=G{j};

        if line1(idx(1))==p

         k=k+1;

         out{k}=line1;

     end

end

line1 = fgetl(f);

end

 end

output={line1,out'};

This code is intended to work as follows:

1. Asks user to input file name

2. From that an excel file is opened that has the following information:

PSA Numbers

R00763

R00766

R00759

R00761

R00767

R00768

R00764

R00757

R00879

R00877

R00881

R00880

R00886

R00849

R00818

R00817

R00860

...

 and a 'txt' file that holds:

PSA_num Client Name Start_Time End_time Category

R00818 Counseling Center of Milwaukee Inc 8/1/2006 Educational

R00817 Milwaukee County Zoo 8/1/2006 Social

R00860 Wisconsin Humane Society 8/28/2006 Environmental

R00860 Wisconsin Humane Society 8/28/2006 Environmental

R00857 Radiology.Org Health

R00856 Clean Wisconsin 8/25/2006 Environmental

...

3.The code is then supposed to compare every number in the first list (A)to the numbers in the second list (B).

4. For every time a number from list A is found in list B, the 'k' should increase. Once the code has gone through all of list A the output should be:

PSA_num Client Name Start_Time End_time Category Played

R00818 Counseling Center of Milwaukee Inc 8/1/2006 Educational 1

R00817 Milwaukee County Zoo 8/1/2006 Social 1

R00860 Wisconsin Humane Society 8/28/2006 Environmental 2

R00857 Radiology.Org Health 1

R00856 Clean Wisconsin 8/25/2006 Environmental 1

I understand that the end of my code is correct, however I can't even get past 'idx' because it is not reading anything.

I think you can make your question more clear, by posting just the part of the code which is not working, and post the error message

Okay, thanks!
