This option does not work, the value given is not the one I'm looking for...
Then you need to be more open minded and pay us to work.
In fact, this option is working: http://jsfiddle.net/thinkloop/XW9AF/
I'm playing with it right now, but, yes, I'll probably pay someone here if he can do what I want, I've already paid another member here for another project, so I guess that I am already "open minded"
How exactly is that not working?
