I have set up a page which when I click the button BlockUI does what is supposed to do as well as jquery Form plugin; however, the success and failure messages are displaying in the blockUI. What I would like is for the success and error messages to replace the form. The code I am using:

Code JavaScript:
 $(document).ready(function() { 
        $('#signup').click(function() { 
            $.blockUI({ message: $('#blockform') }); 
    $(function() { 
        // bind form using ajaxForm 
            // target identifies the element(s) to update with the server response 
            target: '.message', 
            // success identifies the function to invoke when the server response 
            // has been received; here we apply a fade-in effect to the new content 
            success: function() { 

what part of this needs am i needing to modify for it to function correctly?
