使用jquery表单插件动画消息

I am having a problem using the jquery Form Plugin. I have a form that is setup that I would like to animate the errors/success when a user submits incorrect information or gives the user a succes message when then enter correct information. However my problem is twofold. The message that displays on the same page only works in firefox with the jquery that I currently using. What would cause this?
