Hello everybody,
I am having trouble finding a logic for following problem:
Should be true if:
page = 1 OR page = 3, but it should also be true if page = 2 OR page = 3
The result should never contain 1 AND 2 in the same time.
This obviously does not work:
(page = 1 OR page = 3) OR (page = 2 OR page = 3)
This also does not work:
(page = 1 OR page = 3 AND page != 2) OR (page = 2 OR page = 3 AND page != 1)
Has somebody an idea how to solve this?
Thank you in advance for any help!
Merlin
