Fellow Monasterians:

After Super Searching and reading a previous question, and bart's warning I still want to venture this question anyway (I think I have a legit use). But maybe there's another way.

The user clicks one of a dozen radio buttons in an HTML form, all with the name of "type" and values of 1-12 respectively. So, in my Perl:
use CGI;
my $query = new CGI;
my $t = $query->param('type');

So, if they clicked the 2nd button, $type = 2. For reasons too lengthy to discuss here, I want to have the equivalent of: 
$type.$t = 1;  #or $type2 = 1 or $type2 = true

I'm not really relying on the user's input to determine the variable name, as they are limited to a dozen radio buttons, all with set values. I just want to "build" a variable based on their choice. Otherwise, I see the only solution as: 
if ($t == 1) { 
   $type1 = 1;
} elsif ($t == 2) {
   $type2 = 1;
...
}

Seems like a bunch of code to do something that could be relatively quick (and seemingly safe). So, my questions: (1) how do I build this variable $type.$t and (2) is there a better way? Thanks in advance.

Update: davido's informative reply to the original question is worth a read by all. However, I was unable to make it work with HTML::Template (ideas are welcome, but I just need to keep the project moving) so instead adopted ishnid's solution without, I believe, jeopardizing security, at least in this case. Thanks all.
