using smd_if to check custom field data from multiple articles
I need to be able to execute an anchor tag (turn some text in to a link) if, and only if, the custom field data from this article appears in another article. Only one custom field to check here; the value must appear in more than one article so that links to lists of articles with this value are created automatically.
Seems like txp:smd_if is up to the challenge, but I’m new to it and I can’t think of how to use it properly to accomplish this. Any ideas?
