SubVI filter not executable. Undefined error.

[RavensFan]

One thing you can do with express VI's is right click and pick Open Front Panel.  Now you'll get a normal subVI you can look into and possibly see why it is not considered executable.  It doesn't necessarily solve the original problem with the express VI, but you might be able to solve the problem in the converted subVI, or at least provide some insight into what LabVIEW is doing wrong with the express VI.

By opening the Front Panel of the VI as RavensFan said, then the block diagram you can copy the contents into a new VI and save it for use in your own VI. Worked for me with the Filter VI from the Signal Processing Toolkit.
