javascript in php page to use window.open()

["Olga Urban" <olga@xxxxxxxxxxxxxx>]

Hi everyone,  
 
I am trying to open a new window after a successful function call (I
don't want to use <a href. and onclick). Here's what I have, but for
some reason, in IE the new window does not open (I have popup blockers
disabled). It opens in Mozilla, but with the wrong size. What am I doing
wrong here?
 
            if (insert($lname, $fname, $course, $date, $media1,
$media2))
                        {
                        echo "<script type=\"text/javascript\">\n";
                        echo "
window.open(\"add.html\",\"resizable=no,width=400,height=200\");";
                        echo "</script>\n\n";
                        }
            else
                        echo "Error adding a record.";
 
 
 
Thanks.
 
Olga
