Hi hbradshaw,

print Tr ({-align => "CENTER", 
     -valign=>"TOP", 
     -BGCOLOR=>"blue", 
     -font-color=> "yellow", 
     -FONT-FAMILY=> "verdana,arial,helvetica", 
     -FONT-SIZE=> "12"});

will not work, but either 
 
print Tr ({align => "CENTER", 
     valign=>"TOP", 
     BGCOLOR=>"blue", 
     "font-color"=> "yellow", 
     "FONT-FAMILY"=> "verdana,arial,helvetica", 
     "FONT-SIZE"=> "12"});

or 
 
print Tr (-align => "CENTER", 
     -valign=>"TOP", 
     -BGCOLOR=>"blue", 
     "-font-color"=> "yellow", 
     "-FONT-FAMILY"=> "verdana,arial,helvetica", 
     "-FONT-SIZE"=> "12");

will work, in the latters case, because a list is being passed in, and the leading - causes some magic to be done on the list. (makes it into a hash in CGI), and the former because you are passing in a hashref, which CGI.pm understands.
In your original caes, CGI thinks you are passing a list in a functional manner, and treating it as such, without trying to match named parameters.

hope this helps

Update
demerphq is , of course, correct in pointing out that strings before the '=>' containing inline hyphens must be quoted.
