Usage[編輯]
Place
on the top of the category page, replacing "CATEGORY NAMEn" with the names only of the target categories, leaving out the term "Category:".
Each category is displayed only if it exists. If neither category exists, nothing will be displayed.
If there is no succeeding category, you may simply place:
on the top of the category page, replacing "CATEGORY NAME1" with the name only of the target category, leaving out the term "Category:".
If there is no preceding category, then leave the first parameter empty, and simply place:
on the top of the category page, replacing "CATEGORY NAME2" with the name only of the target category, leaving out the term "Category:".

Error checking[編輯]
If more than two parameters are supplied, a warning message is shown when the page is previewed and when it is saved the page is added to a hidden tracking category: Category:Pages using Template:Category pair with more than 2 parameters.
Only the first two parameters are processed. Others are ignored.
If more than two parameters are supplied, the template is unlikely to do what the editor intended e.g.
{{tlx|Category pair|CATEGORY NAME1|CATEGORY NAME2|CATEGORY NAME3}}will ignore CATEGORY NAME3{{tlx|Category pair|CATEGORY NAME1||CATEGORY NAME2}}will ignore CATEGORY NAME2, because a duplicate|character between the two categories causes CATEGORY NAME2 to be the third parameter rather the second
Tracking categories[編輯]
- If neither parameter is a category which currently exists the template will produce no output. This is not necessarily an error; the other categories may simply be part of an incomplete series which will be completed in due course
