Hey has anyone ever used this fancy form mootools check box : http://lipidity.com/fancy-form

I was trying to implement into my php but i'm having a little difficulty and it doesn't really give me too many instructions.

Could anyone help me with how to set this up

i know in the form i think it's just <input type="checkbox">Blah blah blah</input>


but then i'm not sure what variable and such i'm suppose to use to know whether it's been checked or not.

Thanks
