15: Tag pair already used
This error message has been obsolete since version 28 of the Aneamal Translator. A related error message is 220: Tag combination already used to tag an item.
Legacy information
While you can use the same tag as often as you want in a simple tagged list, double-tagged lists require that any tag pair is only used once.
Solution
Make sure you don’t use the same tag pair twice within the same tagged list. However, order does matter, so <France><Belgium>
is different from <Belgium><France>
and both can be used in the same list. For example, this could be a list of results from football matches from a Word Cup qualification group, where the home team is named first. So <France><Belgium>
and <Belgium><France>
refer to different matches, one in France and the other one in Belgium.
