Hey guys. Right now, the rankings go from 1 to 10. I'd like them to go from 0.1 or even more preferrably 1.0 to 10.0 in increments of .1. I have tried to edit the code myself but all my efforts have failed. Your help would be greatly appreciated. Here is the code:

// rankings
// grab ranking names
$ranks = explode(',',setting('article_ranknames'));
// set up selects
$options[''] = '-1';
for ($i = 1; $i <= 10; $i++)
{
$options[$i] = $i;
}
$count = 1;
while (list(,$r) = each($ranks))
{
trim($r);
if (!empty($r))
{
$form->AddSelect($r . ' ' . ARTICLES_RANKING, 'rank_' . $count, $options);
}
$count++;
}
