TypeError in TemplateController

Rails
1

Hi
I am new to Ruby programming… I am facing one problem. I am
displaying the files under a particular directory. I have kept all the
directories as hyperlink. I have coded in such a way that when i click
on a particular directory it has to display all the files under that.

But iam getting an error ’ TypeError in TemplateController
can’t convert nil into String’ when i click on the link.

This is the code snippet where iam taking all the files

for file_name in 0..array_count-1
  if(@clicked_file==$subdirectory_files[file_name])

render_text("Selected file : " +

$subdirectory_files[file_name]);
filepath=$theme_root + “/” + $current_directory + “/” +
$clicked_link + “/” + $subdirectory_files[file_name];

    File.open(filepath,"r") do |f|
        f.each_line { |line|
        $theme_files=$theme_files+line;
        }
        end

  end
end

This is the code snippet in .rhtml file

<% if(!$subdirectory_files.empty?)%> <% $subdirectory_files.each do |file_name|%> <%= link_to_remote file_name, :update => "files",:url => { :action => "get_file_data", :id => file_name }%>
<%end%> <%end%>

Please anyone help in this regard

Thanks,
