Lua J1939 filters are not working on Win10

While this may not be your issue, when comparing two different builds of Wireshark it's helpful to state the version numbers of the two versions.

On my MAC it is Wireshark 2.2.1. On my Win10 I tried initially with newest (2.2.6) but to be sure I also tried the 2.2.1 on my Win10. It is the same. Both win installations are not working ane are giving the same error.

Can you post the full contents of your Lua script.
