Subject: Re: cgi params in ruby


Thank you both for helping me with this.



This an error I am doomed to repeat I'm afraid because I understand 
Hash.map and join systax (and didn't think it existed because ri didn't 
list it under the  Hash method).

Hash.map would map to an array of key val pairs I suppose...where val 
would be an array still.  Then text fields get generated with <br>... 
Then when I .join it's doing what?

Thanks.
