Hi sky,

 

please clean up your VI at first!

Most of those case structures are pure Rube-Goldberg!

Way too many property nodes, mostly used to replace local variables!

Best regards,

You are misunderstanding Gerd's post.

 

He is telling you he can't give you a solution because the VI is so messed in the basics of LabVIEW style and good programming practices, he can't tell what is going wrong in the actual functioning of the VI yet.  Heck, you may even stumble across the problem yourself in the process of cleaning it up!
