You need to use a table then iterate through all the values. For example:
local subtype_f = Field.new("lldp.ieee.802_1.subtype") local myproto = Proto("myproto", "My Proto") function myproto.dissector(buf, pinfo, treeitem) local subtype = {subtype_f()} if subtype then for i in pairs(subtype) do if subtype[i].value == A_SUBTYPE then -- do_something elseif subtype[i].value == B_SUBTYPE then -- do_something_else end end end end register_postdissector(myproto)

And if you only want to deal with the last subtype, then of course you don't need to iterate though all subtypes, just check the last one, e.g.:
if subtype[#subtype].value == A_SUBTYPE then
-- do_something
end
