Does the data show up when you hit "refresh", or is it not being inserted at all?

Put a debugging line into your code to see if things are working as planned. Here is one way to do it:

PHP Code:


			
$sql = "INSERT INTO table2 (username,password,name)VALUES('$field2','$field3','$field4')";
$result = mysql_query($sql);
if(!$result) {
     echo mysql_error();
     exit;
}
