Hi

You're probably better off in the rubyonrails mailing list instead of 
the ruby ML.
However, a short answer anyway: to change values on the server side 
(that's where your ruby code is) upon client side events (where there's 
no executed ruby code anymore) you'll need a client side code such as 
javascript e.g. using ajax to communicate that event to the server side.
On another note: you do NOT want a global variable there. A global will 
be used not just for that single user but for all happening to be served 
by the same instance of ruby.

Regards
Stefan
