Subject: Simple Script Help (New to Ruby)

Hello Ruby Masters!

I'm attempting to write a very simple guessing game script in an effort 
to expand my knowledge about the Ruby Language. I'm running ruby on my 
OpenSuse Linux 10 box at home. I'm typically a web-programmer, but I 
want to get into something a little more deep.

Here is my little script:

----------------
# set the default result
theResult = 0

# create the random number
theNumber = rand(10)

while theResult != 3
        print "Guess my number: "
        theGuess = gets.to_i

        # return key
        # 1 = number is lower
        # 2 = number is higher
        # 3 = number matched!
        if theNumber < theGuess
                theResult = 1
        elseif theNumber > theGuess
                theResult = 2
        elseif theNumber = theGuess
                theResult = 3
        end

        case theResult
                when 1
                        puts "My number is lower."
                when 2
                        puts "My number is higher."
                when 3
                        puts "You guessed my number!"
        end

        print "The Result: "
        print theResult
        print "\n"

        print "The Guess: "
        print theGuess.class
        print "+"
        print theGuess
        print "\n"

        print "The Number: "
        print theNumber
        print "\n"
end
----------------

and here's my output when I run it:

----------------
utdream@dream:~/ruby_scripts> ruby guess_number.rb
Guess my number: 1
The Result: 0
The Guess: Fixnum+1
The Number: 3
----------------

The result staying at 0 tells me that NONE of my comparisons worked. Can 
anyone tell me why? I'm sure this is something simple but any help would 
be appreciated.

Thanks in advance!

Warm regards,
