Passing the following Rspec Test

I am trying to pass Rspec tests in ruby and am having issues with this one: Rspec:

it "should valiate secret contains four accepted uppercase characters" do
                @game.secret = "XXXX"
                secret = "RRRR"
                valid1 = @game.checksecret(secret)
                valid2 = check_valid(secret)
                valid1.should == valid2 && @game.secret.should == secret && valid1.should == 0
end

Here is my code (that does not work)

def secret(secret)
    @secret = "XXXX"
    secret = "RRRR"
    valid1 = @checksecret
    valid2 = check_secret
    valid1 = valid2
    valid1 = 0
end

I am new to programming so any help would be appreciated, Thanks
