But if I create a name such as, for example, "color", I'd need to access the form variable thusly: form.vars.color. Since the name was created on the fly, how can I actually say "form.vars.color"?? If the name was created and stored in a variable, say, x, I can't say "form.vars.x". I guess I don't quite understand Python's capabilities.
