ok i can understand that i have already declared $treeout before. But I think that all the information of the tree that i need is stored in $treeout and i cant use it. Just emptying $treeout with undef has no point at all.

Ah, ok, now instead of code fragments, we're going with thought fragment?

Why don't you post the whole code?
