You can also write this as
${'composer'.$countything}
But I'd really, really suggest looking into using arrays for this -- it looks much
more like an array-ish problem than a variable-variable-ish problem to me. Using
arrays, your input fields would look like:
<input name='fcomposer[$countything]' type='text' size='20' maxlength='60' />
and then your processing code can easily address $fcomposer[$countything] etc.
Cheers!
