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.
