Bad, bad title, I know ;) (Not sure what happened the last time I tried to post this. . .) I'm trying to publish stats for our hockey league on a web page. Early in the program, I load a hash with the names of each team, and an abbreviation for each. For example: 
Abv   Team
------------------
WSH   Washington
BUF   Buffalo
ANA   Anaheim
CMB   Columbus
NJ    New Jersey
ATL   Atlanta
MTL   Montreal

[download]
To make sure I loaded the hash correctly, I used the following code to dump the contents of the hash to a page: 
for my $key (keys %teams)
{
  print $key . " - " . $teams{$key} . "<BR>\n";
}

[download]
Where %teams is obviously the list of teams, where the abbreviation is the key and the name of the team is the value. The above code did what it was intended - it printed a list of all 30 teams in the league.

The next step was to read through a comma-delimited file (using DBI and DBD::CSV) with the desired stats (what's above and below this works fine): 

while (my $row = $sql->fetchrow_hashref)
{
  my %row_data;

  $team = $row->{'Teams'};

  $row_data{TEAM} = $teams{$team};
  $row_data{GP} = $row->{'GP'};
  $row_data{W} = $row->{'W'};
  $row_data{L} = $row->{'L'};
  $row_data{T} = $row->{'T'};
  $row_data{OTL} = $row->{'OTL'};
  $row_data{P} = $row->{'P'};

  push(@table, \%row_data);
}

@table is an array I hand off to HTML::Template to build a result table. The table prints as intended, however, all of the team names are blank. But if I change this: 
$row_data{TEAM} = $teams{$team};

[download]
to this: 
$row_data{TEAM} = $team;

[download]
I get the abbreviation for the team I intended. Even stranger, if I change the line to this: 
$row_data{TEAM} = $teams{"NYR"};

[download]
I get NY Rangers to show up for all 30 teams. Why are my hash values coming back blank?

I tried doing a super-search for the above problem and didn't seem to turn up anything. Can anybody shed some light on this? It's really frustrating me. I had to put down perl for too long a time (how dare work interfere with something fun ;) and thought I'd get back into the swing of things with something easy.

Thanks in advance,
