Hello all!

I have two questions to ask:

1. I need a bit of help with an infobox. What I want to do is the following:
 * tag1=
 * tag2=
 * tag3=

Each higher tag is dependant on the lower tag. Meaning tag3 cannot exist without tag2 which in turn cannot exist without tag1. As such, I want that whenever I input values for either tag1 alone, either tag1 and 2 or all three tags, a certain category to appear. There is a problem though. If there are values only for the first tag, only a category to appear. If there are values for the second tag2 too, only a category to appear. This means that using won't help simply because it will add the category for tag1 and I don't want that to happen. As such, is there a way to exclude an automated category if I input values for the other tags?

If my question still doesn't make sense (English is not my native language), I'll try and re-explain it.
 * If tag1 is the only one with value -> Category1 will appear
 * If both tag1 and tag2 have values -> Category2 will appear, but not Category1
 * If all three tags have values -> Category3 will appear, but not the other two

If it's still not clear enough, please tell me and I'll try to make it even clearer.

And now unto the second question: 2. Is there a way to see if a redirect is used (i.e. if it's present on a page) without having to check each redirect individually on special:listredirects?
