Hi

I’m trying to create a simple HTML form with just one drop-down box (a  
select tag, I guess) and a button to submit the selected value, and my  
app has no models. Can anyone point me to a good reference or perhaps  
a code snippet?

Thanks.  
Jennifer

Well, I think I have the form itself right, but I’m not getting the  
value back in the controller. I have this in my form:

\<% form\_tag :action =\> ‘seeimage’ do -%\>  
\<%= select\_tag ‘operation’, options\_for\_select(%w{ Grayscale LookupOp  
RescaleOp  
}) %\>  
\<%= submit\_tag “Submit” %\>  
\<% end -%\>

And then I have this in my controller:

@data = params[:operation]

And then I have a case statement.

What am I doing wrong here?

Thanks.
