I'm not surprised that it won't work in UBB. It looks as though Robbie used a part of it in his sticker without the search ability.
I copied and pasted your modification of the Woodland sticker. I'm still getting unwanted text from the code with the sticker. That's why I eliminated the first line originally. Obviously, I'm leaving something in, or out.
It looks like this.
