I think you're going about this the wrong way. You should use a two
dimensional array for your value; it will be much easier in the long run.
Your input statement should look like:
<input type="text" name="howmuch[]"... >
Then your $_POST elements would be $_POST['howmuch'][0],
$_POST['howmuch'][1], etc.
You can also then use foreach($_POST['howmuch'] as ...)
to go through the 'howmuch' elements in the $_POST array.
