refreshing a div tag after form submission - ajax (jquery)

I have a bizzare issue that I haven't been able to resolve no matter what I try. One section of ajax code refreshes the div tag successfully after form submission - exibit no.1, while another identical section of the code somehow does not want to refresh the same div tag - exibit no.2.

The only difference is that the form that is submitted for exibit no.1 is in the same file (monpanel.php) in which also the div that needs refreshing lies, while the form that accesses exibit no.2 lies in another file (monform.php) and tries to refresh the same div present in the monpanel.php.

The uid2 variable is passing to the .js file and that section of the code successfully (alert outputs the correct uid number) as the alerts show, it even goes all the way to the "success" alert, but the div STILL doesn't refresh. How frustrating :)

In monpanel.php is this

<input type="hidden" id="hidUid2" value="<?php echo (intval($uid_form)); ?>"/>

call to set the variable uid into the .js file (validate.js) in which both of these functions to process the forms and refresh the div tag lie. In monform.php it is similar:

<input type="hidden" id="hidUid" value="<?php echo (intval($uid)); ?>"/>

Here is the validate.js file (exibit no.1 at the top, exibit no.2 at the bottom):

     // Exibit no.1
 $(function() {  

   $(".button").click(function() {  
     // validate and process form here  

     $('.error').hide();  
       var domain = $("input#domain").val();  
        if (domain == "") {  
       $("label#domain_error").show();  
       $("input#domain").focus();  
       return false;  
     }  
        var com_domain = $("input#com_domain").val();  
         if (com_domain == "") {  
       $("label#com_domain_error").show();  
       $("input#com_domain").focus();  
       return false;  
     }  
        var cemail = $("input#cemail").val();
        var port = $("select#port").val();
        var active = $("input#active").val();
        var uid = $("input#uid").val();
        var main = $("select#main").val();

         .hide()

         });

If your

alert("Success!");

is properly being called, my guess is that selector you're using:

$('#list_monitors').html(html_data);

Is returning 0 elements, so the HTML never gets added.

I can't verify that for you without seeing your HTML code, but in that success function, try seeing if $('#list_monitors').length > 0. If it's not, then the problem is in your markup/jquery selector.
