b737 offset & hold probs

Hi all,I'm experiencing some problems with the LNAV, the arcraft doesn't know where to fly to if I set up a hold or an offset. It just flies right, left and then back right etc... I've attached a picture where you can see that I created a hold just before TIGERwaypoint. The airaft doesn't follow the path he should do... When I set up an offset it's just the same problem...Can some solve my problem?Thanks in advancehttp://forums.avsim.net/user_files/99844.jpg
