Yes, use:

username = cgi['username'].strip
profession = cgi['profession'].strip


This will return what you are wanting. Using CGI#params[] returns an 
Array for each parameter (in case it has multiple values). CGI#[] 
returns just a single value (the first in the array), which is what you 
want.


It was useful for me to use:

p username
p profession

to see what was going on. Then read the documentation:

http://ruby-doc.org/stdlib/libdoc/cgi/rdoc/classes/CGI/QueryExtension.html


Hope that helps.
