jquery / javascript question

I am writing a jQuery powered tool that can copy MySQL databases from one server to another one.

In order to support also large tables I want to copy the rows in batches. But it doesn't seem to work. Can someone please have a look and see if I have done something wrong?

main file

 ffunction copyRows(panel,db,tb,start,max) {
        
        busy(panel,'Copying Rows '+start);
           

                alert('ajax/copyRows.php?p='+panel+'&db='+db+'&tb='+tb+'&start='+start+'&max='+max);
                $.getScript('ajax/copyRows.php?p='+panel+'&db='+db+'&tb='+tb+'&start='+start+'&max='+max, function () {
                    busy(panel,msg);
                    if (start !== false) {
                       copyRows(panel,db,tb,start,max) 
                    }
                });            
            

          
        
        
    }

Code (markup):

copyRows.php
note: sql code has been stripped. But if I load the file correctly all output is correct.

<?php

    if ($total == $current) {
        echo 'msg = \'Finished Copying Rows.\';';
        echo 'start = false;';
    }
    else {
        $current = $result['tot'];
        echo 'start = '.($_GET['start']+$_GET['max']).';';    
        echo 'msg = \'Copied '.$current.' of '.$total.' rows.\';';
    }
    
?>

Code (markup):

The problem I seem to have is that even though the copyRows.php file creates the right output, if I do an alert(start); in the main file after I do the call to copyRows.php, the start variable doesn't change but the msg

Any Idea on what I do wrong?

 

never mind. I just managed to get it to work
