jquery form dialog dissapears if i use effect

i am using JqueryUI and everything was fine until i tried to jazz it up and added an effect for showing and closing the dialog. Now the dialog appears and disappears in an instant.

I am using CAKEPHP, if that matter and still have cake.generic.css on and the debug option on, but i dont see how this could matter.

here is my output html code:

and the javascript for the dialog:

                            }
        }); 

I suspect you don't have the effects in your UI.js file. I see you have a custom one. Create another custom one and make sure you have the needed effects - http://jqueryui.com/download
