Allow option value to open 'onclick' from button using chained select
I've created a chained select using an excellent plugin by Mika Tuupola - http://www.appelsiini.net/download/jquery.chained.js
I'm trying to add a simple 'onclick' event to the download button so that it opens up the option value (a linked file) in a new tab - but I cant get anything to work.
I've stripped it down here - http://jsfiddle.net/valleysboy/cB8yB/
The page its based on is here - http://www.cypsp.org/information.htm
Any help would be much appriciated!
