so like you guys said i removed the Pcontains thing because there is
no <p>
and when i first tried he nagged about the return again so i removed
it and therefore ended up with :
var ew=document.evaluate("//strong",document,null,
9,null).singleNodeValue;
ew=ew.innerHTML*1;
alert("Number of earthworms is "+ew);
and when i ran this i finally got output... namely my fishing fever
score (wich is a different number in <strong> a little before the one
i need. (actually the one right before it.
so how can i make him skip the first one and use the second one he
finds.
PS: i allready want to thank all of you for helping me here :p i know
i'm not the most experienced scripter but its nice that others help
you sometimes :p
friendly greets
