Based on what I am reading
here in HTML::Template Tutorial under Example 3, I think you are going to need to ensure that you are not getting duplicates while generating the array of hashes that gets passed to the loop. I don't see how the TMPL_LOOP combined with a conditional would allow you to do this in the template itself.
I could of course be wrong, and would be happy to have anyone point it out if I am.
- ...the majority is always wrong, and always the last to know about it...

- ..by my will, and by will alone.. I set my mind in motion
