[Twisted-web] multiple choice select box

[Alberto Trujillo]

Hello:
I have found a problem with the multiple selection in the select box 
component. I only can receive the last item that I has choosen.
I'm working with html templates plus the nevow files, and I don't know 
how to received all the selection that I have clicked in my form. Here 
there is a part of my code. Can anybody help me?

Thank.
