That couldn't be more vague. Which lines of code are you talking about?

The following works fine for me:

require 'erb'
require 'yaml'

class Listing
  attr_reader :file_name, :data

  def initialize(arr)
    @file_name =  arr[0]
    @data = arr[1]
  end
end

data = ['listingA', 3]
File.open("../data/data1.yaml", "w") {|f| YAML::dump(data, f)}
data = ['listingB', 2]
File.open("../data/data2.yaml", "w") {|f| YAML::dump(data, f)}

data_fnames = Dir["../data/*"]
p data_fnames


listings = []

data_fnames.each do |fname|
  yaml_data = File.open(fname) {|f| YAML::load(f)}
  listings << Listing.new(yaml_data)
end

p listings

listing_template = ERB.new(File.read('listing.rhtml'))

=begin
#listing.rhtml:

<html>
<head><title></title>
</head>
<body>
<% count.times do |i| %>
<div>info <%= i %></div>
<% end %>
</body>
</html>
=end

listings.each do |listing|
  fname = listing.file_name
  count = listing.data
  File.open("../homes/#{listing.file_name}.html", "w") do |f|
    f.write(listing_template.result(binding))
  end
end


--output:--
["../data/data1.yaml", "../data/data2.yaml"]

[#<Listing:0x5d4080 @file_name="listingA", @data=3>,
 #<Listing:0x5d3edc @file_name="listingB", @data=2>]

Depending on what's in your template, I think you could have problems 
with this part:

> listings.each do |listing|
>   File.open("../homes/#{listing.file_name}.html", 'w') { |file|
> file.write(listing_template.result(binding)) }
> end
> 

In the future, copy and paste the exact error message--not your 
characterization of the error--as well a comment in your code where the 
error occurred, e.g.

    #<-------ERRROR HERE*****
