Ok, now that you've said that, the code read makes more sense (not a
programmer! So very much not a programmer!).
Ended up with:
---
/opt/rt3/local/html/Callbacks/MingleCardNumberLink/Elements/ShowCustomFields/ShowComponentName
<%INIT>
if ($CustomField->Name eq 'Mingle Card Number') {
$$Name = 'DisplayMingleCardLink';
}
</%INIT>
<%ARGS>
$Name => undef
$CustomField => undef
$Object => undef
</%ARGS>
--- /opt/rt3/local/html/Elements
% my $output = $Object->Content;
%
% my $MingleCard = $Object->Content;
% if (defined $MingleCard && $MingleCard) {
% my $MingleProject = $Object->Object->FirstCustomFieldValue('Mingle
Project');
% if ($MingleProject eq '') {
% $MingleProject = 'dnr';
% }
% $output = sprintf("<a target='_new'
href='http://URL/projects/%s/cards/%s'>%s</a>", $MingleProject, $MingleCard,
$MingleCard);
% }
<%$output|n%>
<%ARGS>
$Object => undef
</%ARGS>

The documentation is fairly vague on custom callbacks. Thanks to
http://www.runpcrun.com/node/272 for the clue as to where the custom callback
should be located.
