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

Merlin: The variable "page" cannot hold two values at the same time and thus your statement "The result should never contain 1 AND 2 in the same time" is nonsense. Now if you are working two variables, namely $a and $b and you want an algorithm to solve your problem, it's simple. if ($a + $b > 3) { $result = true; } else

    {

$result = false; } Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
