That sounds like it could work, the way i did it is like this, normally clicking that link would make you, for example shoot an oponent with an arrow, While the page script would make the varible FOE go down by ten. if the foes health was already ten or less, then this would kill him, but where the problem lies is that your FOE would survive according to the text. So the link that takes you to that page, has script that reads like this
IF %FOE <11 THEN
BEGIN
$DEST := @P82
END
that way if the page script would kill the FOE, then it would take it to a different page entirely, that way the text doesnt tell you your dead enemy is alive, or let him hit you again. instead it takes you to a page that tells you that your arrow killed him.
