The problem you are asking about is: 
$sql = "select distinct Volunteer from Volunteer where Volunteer =? an
+d Date =?";
my $sth = $dbh->selectcol_arrayref( $sql, undef, $name, $date );

You setup the sql statement but never execute it.|
Update: as particle and jellyfish have pointed out I was off on this. The $dbh handle is undefined at this point.

You have some other problems in your code that are making it difficult for you to find errors like these.
  • You are not running under warnings, I know this because I spotted you problem when I ran this script under warnings and it gave me Can't call method "selectcol_arrayref" on an undefined value
  • You are also not running under use strict


    • You will find it daunting when you first turn on strict and warnings on this script (I got around 45 errors when I ran your script with warnings and strict), but trust as someone who was in a similar situation, It's not that bad. It'll take you 30 minutes to get rid of those errors, but I will <cajun chef>guarantee</cajun chef> you will save hours of debugging.
