Subject: Regexp matching in a block of code

I am trying to create a script that will allow me to compare email
addresses with a list of domains to see if they match.  If they don't
match then everything is good to go, but if they do match, I want to
be able to delete them or move them out of the list.

The code that I wrote gives the following when its ran:
TypeError: type mismatch: String given

method =~	in untitled document at line 7
at top level	in untitled document at line 7
method each	in untitled document at line 5
at top level	in untitled document at line 5
method each	in untitled document at line 4
at top level	in untitled document at line 4
Program exited.

I know my issue is with this particular line: if(add =~
Regexp.escape(comp))
But I am not sure where to find out or how to resolve it

Any help again is appreciated.

Code:

addresses = ["foo1@bar1.com", "foo2@bar2.com", "foo3@bar3.com"]
competitors = ["bar.com", "bar1.com", "bar4.com"]

addresses.each do |add|
  competitors.each do |comp|
    puts "Checking Competitor: #{comp}"
    if(add =~ Regexp.escape(comp))
      puts "#{check} matched"
    else
      puts "No Match"
    end
  end
end
