Check for truth of variable in HTML::Template

stevieb has asked for the wisdom of the Perl Monks concerning the following question:

I am having a brain fart and old-timer moment. I'm tired and not seeing something obvious...

Can I get a Monk to help me figure out how to check for truth when presenting an element with HTML::Template?

I have the following code which essentially sets a done flag to true or false:

    ...

    my $unfinished_bcasts = $Broadcast->unfinished;
            
    my $finished = 0;

    if (! grep { $bcast_id == $_ } @$unfinished_bcasts) {
        $finished = 1;
    }

    $bcast_data->{$bcast_id}{finished} = $finished; 

    ...

I then have an HTML::Template template that has this:

    <TMPL_IF NAME=FINISHED>
        <tr align="left">
              <td><b>Time Finished</b></td>
              <td><TMPL_VAR NAME=TIME_FINISHED></td>
          </tr>
    </TMPL_IF>
[download]

My expectation is, is that the TIME_FINISHED var will appear in the HTML table *if* the FINISHED var is true. My issue is that no matter what I set FINISHED to, the TIME_FINISHED always appears in the HTML. I can confirm with certainty that both variables are being passed along properly to the template.

Please help me with what I'm completely missing.

The fine documentation suggests you need to call `$template->param(FINISHED => $finished)`. Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply] [d/l]

This may be my own fsck up here... please don't waste time on looking into it, as I believe I'm not actually sending the proper data to the template engine... I'll advise if this is still a problem after I confirm my data.	[reply]

Just a little tip, you can debug-output into HTML, too, because it supports comments ;-) `<!-- YOUR COMMENT HERE -->` [download] So you can check your variable used in TT like this: `<!-- Foo: [% Bar %] -->` [download] If you are generating HTML used in a browser, you can also debug to the JS console: `<script>console.log("Foo: [% Bar %]");</script>` [download] PerlMonks XP is useless?
