checkbox formatting...

(using cfmx7, cfform format = flash)

I am trying to use symbolBackgroundColor and symbolBackgroundPressedColor to change the color of a checkbox to ##FF0000, then change it to ##00FF00, once it is checked....it is not working. (per Adobe liveDoc http://livedocs.adobe.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/js/html/wwhelp.htm?href=00000685.htm this is the styles to use)

Does this go inside a style property, or are they standalone properties for the CFINPUT tag, what am I missing?

Thanks!! 🙂
