Can we see the HTML of your select box (btw, is a 'value list' a select box? because that's got me a little confused here...)
I'm thinking that perhaps your options are like so:

If you haven't set the value attribute, I don't think you can reference it and expect to get a value.
Aside from that, I don't actually see anything wrong with that part, although the line with the smiley face looks odd..
Hope that helps,
