It sounds like your PHP code is not being interpreted at all. If you look at the source code via the browser, do you see a <?php tag in there? This should not happen. If this is the case, your PHP code is not being recognized.

For example, looking at the source in Firefox, if you see something like this, something is wrong with how PHP is executed: image of PHP code that isn't executed

Any <?php tag that can be seen in the browser's source code is a problem.

By the way, be sure to put strings into quotes. You are using things like $_POST[u1] where it should be $_POST["u1"] or $_POST['u1']. Only constants should be used without quotes.
