Hi

When you use "Use Default If  Unwired" option for a case structure tunnel, the default value for the tunnel datatype (not a user specified default value) is passed for all 
unwired tunnels. That is, if you have an output tunnel of file refnum type, and you enable "Use Default If Unwired" option, then the default value of a 
file refnum (which is 0) gets passed to an unwired tunnel. The default  values for Boolean, Numeric, and String datatypes are False, 0,and empty 
string, respectively. To further concrete the concept I have attached a simple VI which demonstrates what happens when you use "Use Default if Unwired" option for a case structure tunnel. 

Hope this helps a little and let me know if you have more questions regarding this issue.

Thank you and have a great day!

Hi

I've attached the same VI after down converting it for LabVIEW 2009. Now it should be working for you.
