Try declaring f_marker like so:

local f_marker = ProtoField.bytes("myproto.marker", "MARKER")

Ref:
https://www.wireshark.org/docs/wsdg_html_chunked
/lua_module_Proto.html#lua_class_ProtoField,
specifically section 11.6.7.24.

Also, you should probably start a new thread for each new question you have
rather than continue an old, unrelated thread.  You could also visit
https://ask.wireshark.org/ to search for answers to Wireshark-related
questions or to post your own question.
